connecting 2 IP networks
I have a home network that is working well and functioning properly and the server and workstations use 192.168.1.x addresses. I am configuring a server here at home that I am going to eventually deploy to another site and I have set it up with a static 210.110.10.190 address, which I need to get some of the server's proprietary software to work correctly.
I happen to have a Windows XP workstation on my 192 LAN that has 2 NICs and I've configured the 2nd NIC with the address 210.110.10.189. The server has 3 NICs and all are plugged into a small 5 port switch and an ethernet cable connects this switch to the 2nd NIC on the XP machine. The 192 NIC is connected to my home network switch so it can seel all other computers on this LAN and is able to connect to the internet. After putting the 210 address on the 2nd NIC the result is that now the XP machine and the server can ping each other.
The trouble is that I want other machines on the 192 LAN to be able to connect to the server at the 210 address. I've tried using the route command on the XP machine to try to add a route to the server but it didn't work. I've tried bridging the two NICs in the XP box but that didn't seem to help. Perhaps one of these methods work and I'm just not doing something right, or perhaps they won't work and there is another method. Perhaps I need a router.
Please tell me exactly what I need to do and on which machine and I'll do it quickly and test the solution right away. Thanks in advance for your help.

I don't know why the customer uses that non-private address but they've given me the 210.110.10.190 address to use for this new server so that it fits right into their existing LAN when I deploy it on site. Yes, the software firewalls are all off and I could not get bridging to work.

I don't know what you mean. I can certainly add an alternate ip address for a given nic, but that won't help. Each nic now has an ip address for it's network - one for the 192 and one for the 210 network. Am I missing something?

Ok, fmarshall. Question. So I need to add 2 routes, right?
1 - on the 192 subnet machine (there is really only one machine on 192 that needs to talk to the server on the 210) I need to add a route to route traffic that is destined for the 210 server to the XP machine's 192 address.
2 - on the 210 server machine I need to add a route to route traffic that is destined for the 192 network to the XP machine's 210 address.
That kinda makes sense, but what is the mechanism on the XP machine that sends the traffic sent to NIC on the one ip domain to the other ip domain? I don't need to add any routes to the XP machine? Do I need to turn ICS on and what role does this play?
Getting closer.... Thanks for your help....

"The trouble is that I want other machines on the 192 LAN to be able to connect to the server at the 210 address. "
other machines have two NIC or? ,
other machines are connected in switch or router is between subnets?

Yes, there need to be routes on the 2-NIC XP machine.
I think that ICS will take care of that in view of the IP addresses in use.
At any rate, the routing table for this one should show that packets destined for the 192 subnet go to the 192-addressed NIC and destined for the 210 subnet go to the 210-addressed NIC.

please upload topology picture, we can easier solve the problem

Thanks to fmarshall for the help. It didn't provide a complete answer but basically pointed me in the right direction so I'll provide full points for this answer. One step that was required but missing from the answer was to use the IPEnableRouter key in the registry to turn on routing on the dual-NIC XP machine.

Apparently my question was closed before I posted my summary and the system automatically assigned points. Sorry to all for any inconvenience this caused. My intention was to assign all points to fmarshall but the system assigned them so I hope it did this reasonably.
Thank you!
Have you disabled the firewall of your server and your XP ?
take a look here

by the way is it normal that you using a none private network IP for your server ?
