Comodo Firewall Issues

There are issues with the campus VPN connection for users who are running the Comodo firewall.

If you are running Comodo and want to successfully connect via the Cisco Anyconnect VPN client, one way to address these connection issues is to uninstall Comodo completely.

A second option is to deselect the COMODO Internet security firewall driver from the Cisco AnyConnect Secure Mobility Client Connection network adapter.  To do this:

  • From the Control Panel, open the Network and Internet option and then open Network and Sharing Center.
  • From the left-hand menu, open Change adapter settings, right-click on Cisco AnyConnect Secure Mobility Client Connection and then select Properties.
  • Now deselect the Comodo driver and click OK.

Following this procedure will allow VPN traffic flow through but it will not offer any protection from the Comodo Firewall. 

Note that simply turning off Comodo did not fix the VPN connection problem.
