dhcp relay on a WRT54G

    I am trying to advise a family member on setting up a network at home, and they have two routers and two workstations (I know, far from ideal). To cut a long story short, I am going to need to enabled DHCP relay on one router (and the other one doesn't support it), so this will be the one (basically so the machine on the other rounter can get an address from this router).

    I have seen webpages where it is indicated that it is supported, but I have no idea where to do so.

    Can anyone help?

    The dd-wrt firmware has a DHCP forwarder built-in.

    Just to be clear: Have you got different subnets on the two different routers?

    If so, the 1st router - the DHCP server - will need to serve 2 different subnets. This usually requires special programming. In this case you'll most likely be better off having each router be its own DHCP server.

    If not - if both routers (and their clients) are on the same subnet - you don't need DHCP forwarding. You just need to turn off the DHCP server on the 2nd router so all DHCP clients are served by the first router's DHCP server.
