I was really scratching my head for that forward chain, thanks for clearing out!

[@inprosis]

Mucha calidad, que bien lo explicas he visto el video varias veces , felicitaciones 👍

Thanks for this explanation. Started a year ago with Mikrotik OS at home and in a Museum. Your videos helped me learn a lot especially setting up Capsman. Learning to improve the firewall rules is the next step. Thanks 👍

I started making mass amount of mangle rules "add dist. to address list" for what ever website i use whenever i remember one.. so that my router makes his own database of the IPs that i use..

Thank you for this wonderful video!
I just have a quick question, is there something like an essential firewall rules or filter that should be enabled/ added on the mikrotik?
I'm very new to this and dove head first so apologies for the question.

[@blackwhite-pe7dl]

thx mr for eplanation

[@lev_anni]

Can you please tell, if I want to mark connections/packet destined to specific ip address list from pc to this list (through WAN interface), why only prerouting chain cathes the traffic but not forward chain? thanks

[@MB-xh3tv]

How does this work if you use NAT (like with masquerade), is it traffic going TO the router, or THROUGH the router it self (specially when coming from internet to a VLAN but also the other way around)?

[@kahitanongmaisip9358]

Sir im really learning of your vids is this is same apply in manggle rule? Specifically FORWAR chain

[@erwinbolasa1524]

nice....how about the prerouting and postrouting in the mangle rule?

[@nimsamreth]

thx alot sir...

[@MAICT]

you are welcome :)

[@robertochieng1705]

Thanks Sir How can we identify Thunder IPTV traffic

[@alideziner4819]

plz if u can explain the preotuing and postrouting in mangle

[@user-op5wn7ui3f]

Good

[@MB-xh3tv]

Hi, if you have used a bridge for an other subnet on the same router and NAT to go to an other router, what would I use as chain for the router the subnet lives on: input or forward?

[@MAICT]

on bridge you cannot use the IP firewall. You can only use the bridge firewall

[@jannienortje8347]

Do you have any way to clear connection tracking with a script on Router OS v7 when using failover. Tested and the Scripts just give an error on v7 and on v6 it works without any issues. Your help would really be appreciated.

[@MAICT]

script on Routeros v6 is different than v7. You should adjust it to work on v7

[@chwaseem2716]

Please kindly make a tutorial in which we can bypass any website inside Mikrotik

[@Martin-ot7xj]
