Network puzzle

[BrotherDon]

Hello, We have a unique problem hope you can help. We have 2 offices each has a cable modem and cheap router. 15 pc's in each office. a printer and server in one office (all pc's) that both offices must access. the other has 3 pc's and the rest Mac's with 1 mac server. this side has a catalyst 2900XL switch. Both routers need to serve DHCP if possible.

Can we disable DHCP from a single port on the 2900xl to stop DHCP from crossing offices yet still allow communication to the printer and server? If so what commands to use? We are open to suggestions but tried static IP on one office but caused user problems. (The internet must be served to each office separately) Thanks in advance. PS routers are linksys

Gday Doyne,

I'm not 100% sure what you are trtying to achieve but I think your simplest solution would be to run three vlans/ip subnets in your network.

OfficeA VLAN --> Inter-Router VLAN <-- OfficeB VLAN

You would need to set some ip routes to pass traffic between the subnets but dhcp should not traverse the subnets unless you have an ip helper address set on the routers.

HTH.
