I'm facing some problems on quick start. It install everything but in the end while the filebeat installation, it shows an error and stops the installation
please share the error that you are facing.
Hi, plase help why my admin credentials is not working after I restored the configuration and reboot in opnsense. thank you.
Make sure you are typing the right password, reset with the new and note down.
@@itkb 1234 did not work 🫠
Nice Content😇
Glad to hear that
Do you need to create both single domain and wildcard domain for the pfsense firewall to use ssl/tls for encryption with the letsencrypt certificate and not have the not secure message?
I've created to show the public, otherwise single domain or wild card domain certificate is definitely enough to enable ssl/tls support in pfsense.
Thanks you for your explication. For the certificate can I importe it on Active Directory server ? or just create it only for pfsene ?
In this video certificate is only for pfsense, however can be usable in AD if you know how to do it.
Excellent, I successfully configured the OpenVPN using this video. I used Dynamic DNS in host name resolution. Thank you.
Welcome
How can I enable internet access on openvpn. When connected es vpn I can access the network but not internet. How it can be enabled ? Thank you
In a production environment, OpenVPN will establish a tunnel over the Internet. You should have Internet access though, try ping to an external IP i.e. 8.8.8.8, this should work, later check your DNS settings for name resolution.
I created a new Rule for the OpenVPN by Firewall -> NAT -> Port Forwarding which resolved the issue.
Which port you have allowed in NAT? NAT is solely related for port forwarding, this is not really help to resolve your Internal/ LAN to External/ Internet) traffic.
hello i did follow all video step by step, it connected VPN site to site, but there aren't ping of their ip adrees between siteA and siteB, only do it ping with the ip address of the tunnel, can you help me? what is lacking?
This video is a continuation of “Part-1” of this video series, I would advise you to watch “Part 1” first closely. This Seems you have almost done it, make sure you don't miss and create an OpenVPN rule in > Firewall / Rules / OpenVPN.
YOu know it's not cool to take video without telling anything 😠
Indeed, check my other related videos that covers what's you need
Thankyou very much!! i really appreciate, you saved my job and basically my life😅
Glad it helped
Hello, the tutoriel is great and very easy to understand, however mine is not working and i don't know the reason. I don't know if the problem is related to the "Remote Gateway" on phase 1. Well i have a public ip that is linked to a domain name. They're both pingable. And pfsense is connected to the ISP router which has a local network like 192.168.10.0/24. So i'm a bit confused on what to use as remote Gateway (the public IP/the domain Name/the ISP local router address) ? And on both sites it's the same configuration
IPSec VPN uses UDP ports that are blocked by most of the ISPs, you have to make sure the ISP is not blocking UDP packets, also you can use Wireshark for source to destination traffic/ packet analysis. I would suggest building your local test lab with the same configuration and checking the result, at least you should be confident with your configuration. You could also verify IPSec ports are listening, run those commands share the result with me. netstat -an | grep LISTEN sockstat -l
@@itkb With the command executed only TCP ports are LISTENING. There is nothing going on for the UDP
@@itkb But what is your suggestion about the "Remote Gateway" ?
Waiting for response from peer , what are we doing wrong
Verify IPSec ports are listening, run those commands share the result with me. netstat -an | grep LISTEN sockstat -l
Same here...I remember in using SharedKey Method that we need to setup OpenVPN Server on SiteA (VPN > OpenVPN > Server). Correct me if i'm wrong though
When I run the diagnostic to check the ldap auth it fails I dont know what is the problem, I think maybe it is related to the bind cerdentials. What did you put as ur bind credentials ? I created a service user on my AD and put it in my bind credentials. Can U help me please ? thank you !
You must be making some mistakes in the configuration. Your Base DN should point to your domain i.e. DC=domain,DC=com Authentication containers should point to your service account i.e. OU=IT, DC=domain,DC=com Bind credentials are your service account username in plain text and the password.
thanks for the video, but how were you able to get the static IP of the LAN ?
Watch this video ruclips.net/video/UorByYY4JhQ/видео.html
could you find thwe answer?
Very well done, thank you!
Thank you too!
very good explanation!
Glad you think so!
Do you cut and paste another video at 13:05-13:10???
Nope
@itkb i have do the same but have problem ssl_context_error: OpenSSLContext: CA not defined, Do you have any ideal for fix it? thank you in advance!
You haven't configured your CA and Server Cert, please double check, you are missing some essential configuration at somewhere, follow the exact steps.
we have 2 offices one in delhi and one in ghaziabad do we need public ip to have site to site vpn or peer to peer?
Static IP is ideal, however, you could besides use Dynamic DNS (DDNS).
Hey man I wanted to ask a specific question regarding a specific scenario I have two machines working as servers and one as client where two VPNs are configured. Now I want to route different traffic over different tunnel. Like if I access google it should go through tunnel 1 and if I access yahoo it should go from the second tunnel. VPNs are configured and working fine.
Thank you for your question, i will definitely cover this is my upcoming video's.
Man o man loved your explanation worked like charm
Glad it helped
Kindly sir please upload video how to configure vpn with nord vpn and with pia vpn on pfsense with static ip
Sure
This steps without lose any data?
Yes, its just reset the password.
Nice
Thanks
I have some questions. In my scenario, we cannot perform the CA certificate work, and the user wants VPN access on their mobile as well. In the new mode, there are options for IKEv2 IPsec with MSCHAPv2 and IKEv2 IPsec with PSK, but we have configured it with L2TP IPsec with PSK. Now the challenge is that the L2TP IPsec option is not available in the latest mobiles. How can we overcome this problem? Please share your contact number for discussion
Share the complete details, with pictures,.
@@itkb Sir i can't share here, plz share your email ID or whatsapp no.
Hi Bro can you please make a video on split-tunnel OPEN VPN configuration both server side configuration & client side configuration
I've already covered.
@@itkb bro can you please link me to it. I checked your playlist but could not find split-tunnel for openvpn
Fantastic, worked with 6.7. Thanks
Good to hear
Hello sir, will this apply on the domain-joined PCs automatically ?
Only DCs
@@itkb Thanks for the response, could you guide me on how to implement this across all domain-joined PCs?
I tried make download in the github webste but there don't have the DLL archive. Do you know where i can find it?
The GitHub download URL github.com/ryanries/PassFiltEx is working fine. You have to rename the "PassFiltEx."c into "PassFiltEx.dll" and paste it in the %SystemRoot%\System32 directory. I push you to closely pay your attention to the video and perform all the steps as targeted.
@@itkb Thank you so much my friend! I didn't know what to do since i didn't find the .ddl file in the Github repository.
Thanks for this, I'd been bashing my head on 2 pfSense instances for quite a while to get this going but for some reason your tutorial worked like a charm. Something was going wrong with my routing in previous configurations so it helped to just have someone walk me through it.
Glad I could help!
How would you set up this for all domain computers/users and propagate it through GPO?
Simply follow the video specifically, just copy and paste the files in the c:\Windows\system32 folder location in the Domain Controller, and tweak changes in the Registry. As this is for DCs only, not related to domain-joined PCs or applied through the GPO.
@@itkb I don't see how changes made on the DC's registry will get to the user PC's.
Dear pal, you only have to work in the DCs.
Can you please make a video with OPNsense with a linux LDAP server? like openldap, and show how to integrate the user in the OPNsense platform?
Sure
Excellent video. How do we configure if Both sites have ddns?
Glad to hear that, for dynamic IP, use ddns instead of IP address.

Hello, I'm trying to configure pfSense OpenVPN SSL/TLS and while browsing the internet I found your tutorial which is the most complete I found, however I ran it several times and the last few times I decided to recreate the settings from the Shared Key and without success after carefully following the of the two videos shows ERROR TLS Error, reconnecting both at the headquarters and at the branch (I'm in the laboratory) on virtual machines I'm afraid of applying it in a production environment and deconstructing what has already been done Do you have any tips
Glad to hear this

Hello, I tested your solution, and it's working great. I have a question regarding multiple clients' connection with IPsec. Can you create a How-to for various clients' connections to a central office so branch offices can see each other?
Glad it's working, sure in future i will.
worked for ESXi 6.7. THANK YOU For anyone whos curious, the layout of the entries in the shadow file is: root:$1$xxxx$xxxxxxxx:13355:0:99999:7::: [name] : [ hashed pass ] : [ day since last pass update ] : [ days until password change ] : [number of days before forced pswd reset] : [days before pass reset to notify user ]::: I think you can set the 99999 to 0 and be prompted to change password on next boot, except im not sure if it requires you to know the current password. I also had not tested it, since I just wanted to get back on the machine. Good luck to anyone else who forgot their passwords.
