Having two network cards

Bridge the both network cards, i don't know what OS you are using. When you put the bridge the both networks will see eachother like nothing is between them.

This will require routing (either hardware or software). What you need to do is to tell each interface how to connect to the other. Exactly how you will do this depends on the solution you choose. I would recommend buying a router and connecting it to your network. It can do much more than just route between two LANs...but a simple static route will allow the machines to see each other and access data (dependent upon their permissions, of course).

Hello There,

In order to do that you need a "bridge" software, there are some around you can test. I personally use one called WinRoute from Tiny Software. It is very easy to use and configure and it doesn't need as much hardware and software requeriments such as Microsoft Proxy, which is also very good.
You can try any software that can do NAT (Network Address Translate).
I have a trial version of that software, please e-mail me back if you want to give it a try with it.

Good luck,@lberto

well, if it's windows NT, just enable port forwarding. you can get a router and use WINS, but if it's a small network, just do the port forwarding.

Let call the pc in the middle (current pc which contains two network cards) the PC-ROUTER.

Network card on PC-ROUTER connected to studio's segment, say define ip setting like below:
ip address: 192.168.0.1
submask : 255.255.255.0
gateway : 10.10.10.1

Computers on studio's segment define something like:
ip address: 192.168.0.xxx
submask : 255.255.255.0
gateway : 192.168.0.1

Network card on PC-ROUTER connected to main-office's segment, say define ip setting like below:
ip address: 10.10.10.1
submask : 255.0.0.0
gateway : 192.168.0.1

Computers on main-office's segment define something like:
ip address: 10.10.10.xxx
submask : 255.0.0.0
gateway : 10.10.10.1

On PC-ROUTER, enable forwarding, therefore enabling the PC-ROUTER to function as router.

Should you use workgroup (peer-to-peer), then STUDIO workgroup will be displayed as well as MAIN-OFFICE workgroup in the Network Neighboorhood, and you can access them also directly.

But, domain-controlled network will require trust.

You don't mention what OS.
If the computer with the 2 NICs has Windows 2000/NT/XP you just have to enable IP Forwarding. then use route add on each workstation on either side of the computer that has the 2 NICs.

If you are using Windows NT or 2000 you can set your server to act as a router, allowing both segments to 'see' each other. You may need to use the ROUTE command to enable routing, but it is not really complicated and is a lot cheaper than buying routing softeare or a dedicated router.
