One of the things I’ve been working on for Cobia is a number of use case scenarios showing how it can be used in a home or small business. The first one I created is a simple layout for setting up Cobia as your firewall and DHCP server with a WRT54G wireless AP/router. This one was pretty easy, since I needed to set up this exact configuration for my own home network.
During the process I found out that the WRT54G won’t pass DHCP requests to the Cobia server if you plug Cobia into the WAN port. On the other hand, if you plug it into one of the switched ports on the router, it’ll pass the requests along, since the DHCP request is a broadcast. You learn something new every day.
