2 gateway problem

[Guest]

I have Windows 2000 Server AD Network with XP and W2K Clients.

Most of the clients default gateway reach a WAN, since there are corporate
applications. Some of clients reach internet through a firewalled router. And
some others need to reach both of them.

The actual solution is for some users reach internet trhough a proxy, and
for some others default gateway is switched as needed, through the DHCP
server.

How can the clients reach both Internet through the firewall and the
corporate's WAN without using a proxy nor changing the NIC's default gateway.
That is setting both gateways one for internet and the other only for corp's
applications or web pages.

Best Regards.

It is a bit hard to say without specific information about your network.
But here is a general answer to a general question.

Assume that you have two gateways, one to the Internet and one to a
corporate LAN. For Internet access, you must set the Internet gateway as the
default gateway, because you cannot know what IP address on the Internet you
want to access.

For corporate access you do not need to use default routing because you
know exactly what IP addresses your corporate machines use. You can add a
static route to direct traffic for your corporate LAN to a different
gateway. You can add this route to each client machine, or you can simply
add it to the gateway router to redirect this traffic to the other router.
