Assuming you are not using VLans - If NICexternal is connected to the SOHO
router, it must have a 192.168.1.x address. Depending on the capabilities
of the SOHO router, you may not need NAT on the Win 2000 server. Try simply
enabling LAN routing.

NICexternal should have a default gateway of 192.168.1.1. NICinternal
should have no default gateway, and machines connected to the 192.168.2.x
network should have a default gateway of 192.168.2.1. The SOHO router needs
a static route for the 192.168.2.0 network pointing to the IP address of
NICexternal. If the router does not have this capability, use NAT on the
Win2k Server. You may have problems running NAT behind a NAT router, but
this usually works.
