2 WRT54G + 2 cable modems = 2 LANs connected to each other?

    I have 2 LANS creted with WRT54G + some wired&wireless PCs connected to them. Both routers distribute the Internet (WAN port connected cable modems) via DHCP to their LANs
    I'd like to bridge my both LANs in order to share files hosted on each LAN PCs AND TFTP server running at one of the WRT54G.
    I know there are guides how to connect two WRT54G but they all begin with turn off DHCP on secondary router. I still want to have two independent Internet gateways (one for each LAN) but I also want to be able to both LANs PCs "see" each other.
    Any ideas?

    You can setup a router, or a PC doubling as a router, between the 2 LANs. As the 2 LANs have different subnets (if they don't, reconfigure so they do) you'll need to route between the 2 subnets.

    If you have an old PC (386, 486...) lying around, look at the Linux Router Project, which allows you (if memory serves) to run a router from a single floppy 386 with 2 NICs.

    Alternatively, take one of your existing PCs (running Linux, NT, or higher), put another NIC in it, and configure as a router.

    Make sure not to relay DHCP from the one subnet to the other, or you'll have a bit of a shambles.
