connecting domains on different subnets

[bigkeith]

Hi all,
We have just acquired an adjoining business and would like to trust their domain to ours so we can share some resources. I have borrowed one of their 3com 4228g switches and placed it in our cabinet and attached one of their servers to it. I have then uplinked their switch to ours, ours being a 3com 3300SM switch, using a crossover cable but I cannot get either subnet to talk to the other. If I change the ip address of their switch to one in our range then the uplink works, so the cabling is correct. How can I route traffic from one subnet to the other using the switches I have. Both businesses run on different subnets theirs being 192.168.50.n and ours being 1.1.1.n (not my fault!). Any help would be greatly appreciated.

I believe the problem is simple- the 4228 is not a Layer 3 switch, hence you cant connect between different subnets with it.

I suggest you utilize a small router for the purpose of communicating between the two networks.

I hope this is helpful.
