Routing and Remote access VPN

I have a Windows 2003 server that is a DC, DNS, DHCP and Routing and Remote access server for VPN's.

The external interface is on 172.16.0.10 and the internal is on 192.168.0.10. I have noticed that when a VPN connection is attempted, the SYN packet arrives on the external interface but the SYN ACK is sent out through the internal interface with a source address of 172.16.0.10.

The default gateway is set on the internal interface currently as 192.168.0.1. How can I get the VPN server to reply on the correct interface?

172.16.0.x traffic is already told to route through 172.16.0.10 but it doesn't do it.

Can you upload your routing table here if your problem is not yet solved?

MS recommended setting up VPN with only one interface. Problem solved.
