We have a Windows 2003 Server running ISA Server 2000 with routing and remote access configured to accept VPN connections.
There is no problem connecting to the network with the VPN client except that once connected the clients on the internal side of the network can no longer access the internet.
As a side note, this "lockup" also freezes the ISA server until such time that the VPN client disconnects.
Once the VPN client has disconnected, all functions return to normal.
This is a dual-homed server utilizing static-ip addressing for the VPN clients.
Any help is most appreciated.
