sorry for the inconv i mage to fix the problem.

Why on Earth do you do that? You could just push a route back to the rest of the network to your VPN client.

Anyway, I don't know, that IP your VPN server is, but it should probably be excluded from this rule. If that doesn't help, please paste your whole firewall setup with detailed IP descriptions.
