Title: Avast! Firewall prevents Cisco VPN
Post by: sjumper1522 on December 22, 2011, 10:15:29 PM

Actually the subject isn't entirely true.  I can connect with the firewall on but I can't ping the DNS server and I can't RDP to my workstation on the remote end of the VPN.  If I turn off the firewall, the VPN works as expected.  I want to be able to leave the firewall on when VPN is active.  What do I need to change?

Here is my config.

Avast v 6.0.1367
Cisco VPN client 5.0.07.0440
Windows 7 Home Premium x64

I have added packet rules for ESP (50) In/Out and AH (51) In/Out but that didn't work either.

Hi

Please try this and update us back.

Avast UI -> Firewall settings -> Expert settings -> Friends

add the VPN ip address there.

Then add packet rules for ESP (50) In/Out and AH (51) In/Out.

 
 
Thanks
