VPN Routing Issues

Hi everyone. I'm having trouble getting VPN routing to work correctly on server 10.4.10. Remote clients can connect and authenticate fine, however the only internal IP that the clients can communicate with is the one of the actual VPN server. The only complication that I can think of is that we are using a MPLS network where private and public IPs all work on the same LAN. The only other issue was that I had to move the public IP interface above the private IP because VPN was only binding to the private interface. I initially thought it would bind to all available IPs. So our internal IPs are on two subnets, 10.216.0.0/16 and 10.217.0.0/16. I have those two networks added as private as well as public IP block as private. When I try to ping anything from a VPN client, it routes properly to the VPN server over the public IP but stops there. The VPN server can ping everything internally just fine. It has one ethernet port with two interfaces, one on the internal and one on the external IPs. I have no idea what's going on with the routing on the VPN server. Thanks!
