Using a computer as network router with two nics
I have a prob with a setup I have.
WinXP computer with two nics, one network connected to one and another connected to the other.
What IP addresses and subnet masks do I need to make them communicate. The first network is ok with the computers talking. The second network that I have just introduced cannot see the winXP computer due I believe to my IP/subnet config.
I am setting static IP addresses as usual.
winXP machine
nic1 = IP = 192.168.0.1 subnet = 255.255.255.0
nis2 = IP = 192.168.1.1 subnet = 255.255.254.0
Can't know!

Thanks people
I am using an old existing network for the first nic, BNC coax and the second is Cat 5 RJ45, a stop-gap until It can be completely rewired. (not what I call brilliant)
Thanks fishmonger, I did some searching and found I didn't need to change the subnet mask just the IP range. Not sure what you meen by route command and the -p switch and where to put this if I were to do routing fully.
I am using the winXP machine only from the second network so I dont need it routed to the first network. (winXP machine is Internet and Print server and file server)
Jivco thanks for the Reg key I will use that at some time.

If you are looking to use your Windows XP box as a router, one of the first things you will need to do is enable IP forwarding. Previously, NT and 2000 provided a checkbox in your network settings GUI to easily turn routing on, but with XP it's no longer an easy-to-toggle checkbox. But, given the following registry edit, you'll be on your way to routing packets from one network to another. Set this key to one to enable routing, or zero to disable (disabled is the default):
HKEY_LOCAL_MACHINE\SYSTEM\
