two ip addresses and two gateways - response to incoming request problem

Hi,
my configuration is the following:
1 server windows 2000 with a sigle NIC, 2 ip numbers (192.168.1.4 and 194.243.254.4) actually the default gateway is 194.243.254.62 and the secondary gateway is 192.168.1.1.
194.243.254.62 is a firewall without natting and it is public
192.168.1.1 is a firewall with NAT to a public address (different carrier)
My problem is to correct answer back to a request coming from one carrier or from the other.
For example, if a vpn connection is coming throu 194.243.254.62 the answer goes back to itself and if a vpn request coming from 192.168.1.1 the answer goes back to 192.168.1.1.
For the fixed ip addresses of users i haven't problems using static routing, but, often i don't know this addresses becouse they use diaulp connections.
May somebody help me??
Best regards.

You cannot have two default gateways.
You will either need to get a router that can handle two connections or specify routes by hand. Only one NIC can be the "default".

I don't think Windows can. You need to take it away from Windows and have both connections going in to a router designed for this job.
You can route the traffic back out for a certain subnet by manually configuring the route paths. (Command "route" from a command prompt).

This don't change the situation.
I already use static routes for the clients addresses i know.
Are the unknown in advance clients the problem.

For the client addresses that you don't know you will have to route everything in through one connection. Windows is not a router and this is a router's job. While it can do some basic routing, not for this type of traffic where you cannot create routes in advance.
