Two Networks, One router, One internet

[damage750]

I've got a test network (192.168.42.x) that has a Windows server, Nortel CS1K, Avaya Definity Cabinet's & IP office's on it, and then there is my production network (10.0.1.x) which my work PC resides on. I wanted to see if i could put a Cisco Router with two Fast Ethernet cards in it in between the two networks to talk to both. I frequently need to make changes on the windows server and it'd be nice to be able to have internet on my PC from the 10.0.1.x network but be able to remote desktop and telnet into my cisco switches & server on the 192.168.42.x network.

How would I go about doing this, static routes? Any help is appreciated. Thanks.

yes, you'll need a default route on the Cisco and then a route on your "core" device to point to the next-hop address that you give to the Cisco. For example, you give f0/0 10.0.1.250 and f0/1 192.168.42.254 to the new Cisco. On the device that is the gateway for your 10.0.1 network (we'll just say it is 10.0.1.254) you'll enter a static route pointing to 10.0.1.250 as the next-hop for network 192.168.42.0/24. On the new Cisco router you'll simply specify a default route pointing to 10.0.1.254 as the next-hop. You either do this or introduce a dynamic routing protocol and have it take care of the routing updates for you.
