EVPN problems, need help

I am using Comodo version 2.3.6.81 on a Windows XP box with Nortel Networtks VPN client software.

The only way I can get the VPN to work is if I turn off the Network Monitor.

Is there a better way to fix this problem? I hate to have the network monitor turned off everytime I use VPN.

Any suggestions? Is there some way to build a tunnel through the firewall for the VPN client?

Thanks,
Fred
