I have 2 offices connected via point-to-point dedicated T1 line. One office is on 192.x.x.x, the other office is on 10.x.x.x. My phone guy who set up the routers said this was necessary, I'm not sure why. The 192.x.x.x subnet also has the DHCP server on it, as well as the connection to the web. The other office needs to have manually assigned IP addresses because they don't get an ACK from the dhcp server. Also, I've had to put a route on the router to allow the 10.x.x.x network to connunicate with the web. Two Test Questions 1: Do I really need 2 subnets? 2: If yes, how do I get DHCP to other office?

1) You don't need to, but it's a good idea. If both offices were on the same subnet, every packet broadcast at one office would have to be sent across the T1 to the other office. That would waste a lot of bandwidth. By segregating the two sites in different subnets, only traffic that needs to go from one office to the other gets sent across the wire. 2) Easiest way would be to set up a DHCP server at the other office.

Depending on what you're using for routers, you could likely set your DHCP up on the router at the other office.

If you only have a few computers at each office you don't really need a DHCP server , just set them with a static IP address. you can use one DHCP server for both subnets all you need to do is set a DHCP relay agent.

the office that I currently have static IP's on is really small (4 pc's 3 printers); so I'll think I'll stick with manual addressing for now (thanks Brian). I did read about bootp forwarding being enabled on routers so that clients on one subnet can communicate with dhcp services on another subnet. I'll ask my phone guy how our routers are setup, but in all likelyhood, I'll just leave then as is. Thanks for the responses you guys.
