A world of thanks, Jeremy, I passed my CCNA with confidence scoring 930. I watched all your comprehensive videos and practiced the labs by building them from scratch which indeed boosted my understanding and confidence. Looking forward to your future videos.

Hi Jeremy, I passed CCNA exam yesterday. I have followed your videos since August when I first started studying for the exam. Your CCNA and Packet tracers videos were like my go-to guide when I stuck on a question. I learned a lot from your videos and will continue to watch your weekly CCNA video. Looking forward to your CCNP videos!
Hey Jeremy. Excellent videos. I got some times for you to put in for chapters when you get a chance... 0:00 Intro 1:04 Things we cover 1:47 What is an ACL? 12:00 How ACL's work? 16:20 ACL types 17:50 Standard Numbered ACL's 31:00 Standard Named ACL's 37:47 Things we covered 39:10 Quiz 43:18 Boson!!! 45:11 Materials Keep it up. I look forward to watching your videos.
You must have done something special in this video because Im doing a second run through on the series and I just got the urge to comment and I see I already have 😂 anyways I was going to say I love these videos so much I was thinking of making my own videos like Mystery Science Theatre 3000 where I just do commentary over your videos. I feel it would be educational. Anyways, thanks again man keep up the great work!
did you do this and did you pass? I think i am just going to use this course along with exsim and possibly netsim, i'm not sure if i am going to use another course
Hi, I know it might be insignificant but there the access-list for the IF to 10.0.1.0/24 can be even shorter and still meet its expectations: access-list 2 remark # MANAGE DESTINATION NETWORK 10.0.1.0/24 # access-list 2 deny host 192.168.2.1 access-list 2 permit host 192.168.1.1 access-list 2 deny 192.168.1.0 0.0.0.255 access-list 2 permit any Since the idea was that all hosts from 192.168.2.0/24 except for one (192.168.2.1) should have access, we can just absorb that entire subnet into the permit any on the end of the access-list. There is no need to make a separate rule for that.
2 Weeks Worth of Studying Awesome Tutorial Waiting for Security, Wireless, and Automation Topics. Thank you so much LODI Jeremy !!! Mabuhay sa Channel mo
Jeremy was a nice class today . It was very clear and specific; good job Jeremy. I keep watching your videos ; I do not loss any one. I love this CISCO CCNA class
Not a single mistake. I'm more than happy. Every day in the work (I dont like) I'm thinking 8 hours to go home and start practising and studying for the CCNA. Another day in the box, I don't have much time to review the ANKI flashcards. But for sure, September, I will start over, and I will join a CCNA camp for sure. I will spend all my time to get the CCNA. Thanks Jeremy your videos are awesome
Really great video. Thank you so much, this helped no end in solidifying my understanding of how to create them, how they work, how to use them and what scenarios to use them in. Much appreciated!
OK, according to the video at 35:50 , the router will reorder /32 entires to process more efficently. Which seems like answer D in the Boson ExSim question. Yet Boson and you had the answer as B. I guess it is the wording of answer D. Thank you, Martin
I'm preparing for my CCNA, and your videos looks so amazing, hope to approve it, and purchase your CCNP curse. Thanks again for these amazing IT's videos.
Thanks Jeremy!! Am 20 years old and am starting college late in a couple months (took couple years off to work and save up). Want to be a cyber sec analyst after work but am looking to get a strong network foundation first. Coming off getting my A+, Net+, Sec+ and CySA+. Decided to diversify vendors lol
Coming back from IPv6 to IPv4, all the previously difficult to remember addresses became so simple to remember after looking at these hexadecimal numbers going all scary tbh.
I just passed my CCNA exam a few days ago. This video series was very helpful in learning the material. Thank you! Protips for anyone taking the exam: learn how to read routing tables and rules for route selection, static and floating static routes, HSRP rules, PaGP/LACP rules, a bit of LLDP/CDP. Also study up on wireless LAN controllers, some automation (JSON, Ansible, Puppet) and routing and switching basics, like frame flooding. Best of luck to you all.
Hi Jeremy, First I would like to say. I'm so appreciate from your such a great teaching. I'm watching and following your each and every video. My last request from you is the one, Please leave me your this lesson note in PDF or in word formats. Thank you.
Dear J: Your videos are generally GREAT. One of advice from a former ARAMCO corporate trainer, maybe it would easier to understand and present if you just used pointers or said PC A instead of reading the network addresses. Just a suggestion. Otherwise GREAT!
Great work Jeremy. I've learnt or learning a lot from your videos .Never seen anyone explaining so well on Networking topics like you do. I would like to know if you will be covering any Security side topics as well in these videos ? Something on Interface-base Firewall ,Zone-based Firewall , VRRP, Firewall rules .?
Hi Jeremy, this is my first time watching your videos, and you are too good! Anyway, I'm preparing for my ccna exams. for years I have been learning ccna but it seems I don't have the courage to take the exams.
Very ihelpful Tuto and well explained as usual. for the first quiz , for me seems the ACL 3 is more accurate , because it should also permit only PC1 and 4 , means it has to deny the remain PC in both subnet. is there any one else has noticed this remark? Br.
The implicit deny is present, so there is no need to deny the remaining PCs in the subnets. And because of the ‘permit any’ at the end of ACL 3, other devices such as R1 and SRV2 will be able to access SRV1, so it doesn’t fulfill the requirements anyway.
Jeremy, I hope all is well with you. Thank you for taking the time to reply to all of my (and everyone else's comments)! I've stepped back and took a macro view of how far along I am in the process. I have roughly three months until my exam so I wanted to re-evaluate my study plan. I think IPv6 has tipped me over the edge in terms of knowledge retention and I'm definitely going to need to come back to it, which brings me to my question if you'd be so kind to offer your opinion? Do you think that continuing learning each of the subsequent subjects is the way to go? Even in a situation where I feel I have not taken in enough information to be competent in some of the subjects I have already covered, I'm trying to balance the fine line between understanding the new concepts and pushing through the course. I think my plan is to set up a schedule for each day of learning. I definitely know I need to revise but is it best to blitz through all the content and then return with a revision plan or go for a split learning style of sorts, perhaps between 1 to 2 hours per day, with one day of rest. I may go for something like on days 1, 3, 5, new subjects and on days 2,4,6 I go for revision? I know for sure I have not done enough lab stuff yet so I may go for the Boson offering as you mention in your videos. Speaking of.. (I know this is getting long-winded (sorry) but this is the first exam I have studied for out of school and I'm solo, I don't know anyone else who is following this path) do you think this is a solid approach? This is my list of resources and the order I use them: Learning concepts (1): a) Use you as my primary source of information on topics b) Use Neil's course as a backup if I need a different way of approaching a subject in case I am not understanding it c) Supplement extra required knowledge with Google Labs (2): a) Both your and Neils labs b) ??? Do I need an alternative like Boson or will the labs provided above be enough Practice exams/questioning (4): a) Google (as a filler until C) b) Your flashcards c) Boson practice exams when closer to the date Sorry for the near essay-length comment, I think now that the exam is set in stone, I'm really trying to dig deep and make sure I give myself the best chance which has manifested into the above! - Stuart
If you're feeling overwhelmed, I think it's probably a good idea to hit pause and review/consolidate what you've covered so far. Another approach is to just move on and come back to the difficult topics later, but that's not usually how I do it. Your approach sounds good to me, as does your list of resources! I think with my labs and Neil's labs you'll be fine. Definitely use Boson ExSim, but NetSim isn't as essential of a tool in my opinion, considering the other options out there. If I could add one thing, it would be the official cert guides (vol 1 and 2) by Wendell Odom. They're quite thick books and you don't have to read through all of the chapters, but for getting the details on specific topics I think they're the best resource.
28:46 Sorry I think there's a little mistake : did you mean "If I applied ACL 1 inbound on R1's g0/1 interface, it would prevent all PCs in the subnet except PC1 from accessing anything outside of the local network" ?
I got you noahroach. I too thought the same but that's not correct. Let's look at the network by a third-person perspective. Imagine we are Pc1 and 2 living in our network ( 192.168.1.0) now, we want to meet our friends namely Pc3 and 4 who are staying in their house ( network 192.168.2.0) Firstly, we have to get in (INBOUND) Router 1 via G0/1 interface and we have to exit ( OUTBOUND) via G0/2 interface to say hi to our friends. Now, tell me is that a INBOUND or OUTBOUND.
P.s. your English is very non-native-friendly, in pronunciation as well as in vocabulary/expressions used. I understand you very well, even if I play the video faster. I wonder if it's because you live in Japan.
At 13:45, anyone can help me on how the dest ip add 192.168.1.1 isn't (in theory) part of the network 192.168.1.0/24 and the network 192.168.0.0/16 BOTH. Can't we assign the address 192.168.1.1/16 in the 192.168.0.0/16 network? am I messing something.
thanks for the fast reply, I know you want to highlight the importance of the order of the ACEs, but still wouldn't it be a problem (in the context of Acls) if two hosts have the same ipv4 address in two different subnets, or does the fact that these are private (yet to be NATted) addresses allow for such trickery? Side note: I really appreciate your work and time.
Hello Jeremy, I love the course, I have finally caught up with your videos and invested in both net-sim and ex-sim. I was wondering what is the predicted lecture & lab day for the entire course to be completed day 40? day 50? just curious to get an overall picture on what more needs to be covered. Thanks for the course so far its been the best out there keep up the good work!
Hi Jeremy, thanks a lot for this material and excellent explanation that helping me to understand most of the topics.in day 34 ACLs , as I watching the video exactly at 12:24 why the packet been discarded, it does not match the first ACE not same subnet . so would you please review this point and tell if I'm wrong.
Hello Jermy, you are doing a very good job. I am learning CCNA from your videos, just wondering if I can get any discount voucher for CCNA exam. I am student and cannot afford the whole amount due to financial constraint.
Can someone please help with this question? 35:14 permit 192.168.2.0 0.0.0.255 - Is this ACE necessary? Since there is a permit entry at the bottom, all the source IPs not explicitly denied are allowed. Why do we explictly allow this range? Thanks.
Hi @jeremysITLab If using ip any at end of ACL statment won't allow other traffic from inside to outside and outside to inside. Wont it cause any potential vulnerabilities.
28:48 "If I applied ACL 1 inbound on R1's G0/1 interface, it would prevent all PCs in the subnet except R1..." Is that correct? Not "...except PC1..."? (Or I should improve my English. :) )
At 16:20 There is an implicit deny at the end of all ACLs. In this sentence, I think in place of ACLS, ACEs will come. What you think Jeremy, am I right?
Hi Jeremy. For Quiz 1/Question 1, May you please explain why the other answers are wrong? one of the other answers looks right to me. Second, you said in the video, when going through the ACL, if there's a match it will not process the rest of the list; it will stop once there's a match. So for quiz 1 correct answer, wouldn't it mean that it would process "10 permit 192.168.1.1" and not process "20 permit 192.168.2.2"?
I'm still learning myself however based on the requirements to specifically only allow access to the network in question "10.0.1.0/24" from pc1(192.168.1.1) and pc4(192.168.2.2) out of the available options it would be the only that does this due to the implicit deny that will stop any other traffic which doesn't match the two host entries in ace 1 and 2 . The other options go outside the scope of what is required ACL2 would actually permit all host from the 192.168.1.0/24 & 192.168.2.0/24 networks(PC1-PC4) but then deny all other ips not within those subnets .ACL3 does permit access to the host PC1 & PC4 while denying other host from the same subnets only however in the last statement it allows other subnets for instance maybe there is a subnet 192.168.3.0 and those host will be able to access the server. Finally ACL4 in one of the ace entries denies one of the host 192.168.1.1(PC1) that we need to allow access for which would automatically make that option wrong keep in mind that isn't the only thing wrong with that ACL btw but maybe watching the vid again may help.

Note that at minute 37 - you check the list according to the order it is shown rather than the ACEs number

Outbound applies to packets being sent out of an interface, inbound applies to packets being received by an interface.

At 13:45, anyone can help me on how the dest ip add 192.168.1.1 isn't (in theory) part of the network 192.168.1.0/24 and the network 192.168.0.0/16 BOTH. Can't we assign the address 192.168.1.1/16 in the 192.168.0.0/16 network? am I messing something.
You’re correct, it is part of both subnets! But I never said it wasn’t ;)
thanks for the fast reply, I know you want to highlight the importance of the order of the ACEs, but still wouldn't it be a problem (in the context of Acls) if two hosts have the same ipv4 address in two different subnets, or does the fact that these are private (yet to be NATted) addresses allow for such trickery?
Side note: I really appreciate your work and time.
On 35:16 , you didn't need to permit 192.168.2.0 0.0.0.255 right? It would be allowed anyway with permit any, and the ACL would still only block PC3
Thanks miilion
Hello Jeremy, I love the course, I have finally caught up with your videos and invested in both net-sim and ex-sim. I was wondering what is the predicted lecture & lab day for the entire course to be completed day 40? day 50? just curious to get an overall picture on what more needs to be covered. Thanks for the course so far its been the best out there keep up the good work!
Probably about 50 to 60 days
Hi Jeremy, thanks a lot for this material and excellent explanation that helping me to understand most of the topics.in day 34 ACLs , as I watching the video exactly at 12:24 why the packet been discarded, it does not match the first ACE not same subnet . so would you please review this point and tell if I'm wrong.
LOL Block Bob From Accounting
great
Hi Mr Jeremy I hope you're doing well
Can you explain to me in quiz one
When you chose ACL 1 OVER ACL3 ???
I think I found the answer in your video
If a packet doesn't match any entries the packet WILL BE DROPPED
so the best answer was ACL1
Hello Jermy, you are doing a very good job. I am learning CCNA from your videos, just wondering if I can get any discount voucher for CCNA exam. I am student and cannot afford the whole amount due to financial constraint.
Can someone please help with this question? 35:14 permit 192.168.2.0 0.0.0.255 - Is this ACE necessary? Since there is a permit entry at the bottom, all the source IPs not explicitly denied are allowed. Why do we explictly allow this range? Thanks.
super. thanks a lot ❤
Hi @jeremysITLab
If using ip any at end of ACL statment won't allow other traffic from inside to outside and outside to inside. Wont it cause any potential vulnerabilities.
28:48 "If I applied ACL 1 inbound on R1's G0/1 interface, it would prevent all PCs in the subnet except R1..." Is that correct? Not "...except PC1..."? (Or I should improve my English. :) )
Thank you Boss
In Quiz Question 3 I got the answer right for the wrong reason.
I misread the list of separate ACLs configured as if a single ACL's statements.
quiz question 3 just not Incomprehensible
I agree, it is not incomprehensible ;)
At 16:20 There is an implicit deny at the end of all ACLs. In this sentence, I think in place of ACLS, ACEs will come. What you think Jeremy, am I right?
'At the end of all ACLs' is correct
@@JeremysITLab ok
Hi Jeremy. For Quiz 1/Question 1, May you please explain why the other answers are wrong? one of the other answers looks right to me. Second, you said in the video, when going through the ACL, if there's a match it will not process the rest of the list; it will stop once there's a match. So for quiz 1 correct answer, wouldn't it mean that it would process "10 permit 192.168.1.1" and not process "20 permit 192.168.2.2"?
I'm still learning myself however based on the requirements to specifically only allow access to the network in question "10.0.1.0/24" from pc1(192.168.1.1) and pc4(192.168.2.2) out of the available options it would be the only that does this due to the implicit deny that will stop any other traffic which doesn't match the two host entries in ace 1 and 2 . The other options go outside the scope of what is required ACL2 would actually permit all host from the 192.168.1.0/24 & 192.168.2.0/24 networks(PC1-PC4) but then deny all other ips not within those subnets .ACL3 does permit access to the host PC1 & PC4 while denying other host from the same subnets only however in the last statement it allows other subnets for instance maybe there is a subnet 192.168.3.0 and those host will be able to access the server. Finally ACL4 in one of the ace entries denies one of the host 192.168.1.1(PC1) that we need to allow access for which would automatically make that option wrong keep in mind that isn't the only thing wrong with that ACL btw but maybe watching the vid again may help.
