I'm trying to set-up an IPSec VPN using Windows 2000 Pro on a computer with Symantec Client firewall version 8.6 installed. The VPN works fine if I disable the firewall but not when the firewall is enabled. The VPN client is the Windows 2000 client. Any suggestions on how the firewall needs to be configured for the VPN to work through it would be appreciated.
BTW, I'm using Openswan on the other end of the VPN tunnel. The VPN runs over a wireless link with WPA enabled.
