ByPass Layer 7 filtering
 

Hello
My network administrator filtered IRC client (Quasel , Xchat , Konversion , ...) with layer 7 filtering in mikrotik firewall/router .
How can bypass this ?

You don't. You should abide by the rules of the network you are using. We aren't going to help you bypass this sort of stuff.

Especially if you don't even say please or thank you.

Okey .
Only one question .
Can bypass layer 7 filtering ? (Yes/NO)

NO. You can't bypass it. You could disable it if you had admin access to the router, but I'm guessing you don't.

and even if you could
We will NOT help you break the LAW
