[SOLVED] Weird problem with uTorrent and Comodo not blocking if VPN drops.

[rayzor 2]

So with the AirVPN outage, I realized that my firewall was not working properly! I have an application rule for uTorrent... TCP/UDP block everything outside 10.4.0.0 -10.9.255.255. However, uTorrent is still downloading away! I tested the rule with Firefox and it works fine. I get blocked trying to use it.. I check the Comodo logs and I see that Firefox is blocked. I also see uTorrent is being blocked, however it still downloads! What givse???

Hello!

Can you please send us a screenshot of the rule which should block uTorrent?

Kind regards

Hello!

The application rule for uTorrent looks ok and the AirVPN Network Zone is correctly defined. Maybe uTorrent is using a proxy? Please also check that Comodo Firewall security is set to "Custom Policy".

As a side note, please check your Loopback Zone definition (it is wrong), it must be IP/Netmask [127.0.0.0/255.0.0.0] or equivalently IP range [127.0.0.0 - 127.255.255.255]

Kind regards

I think the problem was the Loopback Zone definition. I changed that and it works perfectly now.. Thanks!

I would point out that your "Home Network" Network Zone is also incorrect:

[192.168.0.0 - 255.250.255.255] must be changed to either [192.168.0.0 - 192.168.255.255] (IP address range) or [192.168.0.0 / 255.255.0.0] (subnet mask)

It's very important that you don't confuse subnet masks with IP address ranges.

I'm also having this issue with COMODO 6 and uTorrent 3.2.3

Maybe try using Azureus if you don't wanna set up the rules properly. The new client (4.8.0.0 or so) has some force-bind features and it works great! And Vuze is open source ...

It automatically detected that I was using a VPN and bound the Application to the Tap-Adapter. Pretty cool

Thank you so much for that hint, this is a great solution for everyone who doesn't want to use comodo and it works perfectly
