I have a SBS 2003 server that is running DNS/AD/DHCP. Address space is 192.168.1.1. We added a new wireless router to the network to replace a old damaged Watchguard Firewall/gateway.
Everything works well except I can not get DHCP to service from the LAN to the Wireless clients. The wireless clients can ping to the server but it's like they are not getting the DHCP server broadcast.
I have move the DHCP to the router for now and it works i.e. The workstation on both the LAN and wireless are getting address but it is causing some issues with SBS.
This wireless router is also currently acting as the gateway and firewall for the network. So the network looks like this:
Internet > Cable Modem > Wireless Router/Gateway/Firewall > Switch > Local Clients icluding SBS
How can I get the DHCP server to broadcast to both the LAN and wireless clients ?
By default, these wireless routers are setup to put the wireless devices on a separate address space and do NAT. You need to change that and get the wireless router to be a plain access point, not do DHCP and not do NAT.
The specifics about how to do this depend on the router model, and I almost certainly can't tell you how to do it, but I doubt it is particularly tough once you know what you are looking for.
