How to Block Skype Using Layer7-Protocol

Hello All
I thought of Sharing this with all, How to Block Skype using Layer7 Protocol without blocking others site.
Lot of experiments I have tried which Block useful site and did not block Skype itself.

Hope this work for you also because I have these implemented in about 12 different sites currently and it work fine.

Firstly, Update you RB or CCR to the latest current OS Version at least V6.39.2

Layer 7 Tag:
/ip firewall layer7-protocol
add name=“Block Skype” regexp=“^.+(skype|skype.com).*$”

Now apply the firewall filter rule to activate the block.
/ip firewall filter
add action=drop chain=forward comment=“Block Skype” layer7-protocol=“Block Skype”

You can modify the rule if possible.

Let me know if this Help!

Its not working for me.. :frowning:

This method does not affect HTTPS traffic. You can try different approach. Intercept and forbid DNS requests containing skype as keyword. They are not encrypted.
