    i use Tomato on a WRT54G and i love it, best firmware for this rig !

    I need more ethernet plugs, so i figured i bought a BEFSR41 (official firmware inside).

    Problem is i don't know of to configure it as a simple switch.

    here is what i did :

    on WRT54G (, I declared the SR41 mac adress and asigned it a static ip

    on SR41 i declared it as, same subnet, and disabled DHCP, leaving it on Obtain IP dynamically.

    Now here is my problem : if i plug the SR41 on my ethernet port 4 of my WRT54G, and plug the cable on port 1 of SR41, i can see from my lan PC the SR41 webpage (typing and i can plug a PC seemlessly that will look being pluged to the WRT54G (cool). BUT the thing is i'd rather have my 4 ports free and use the "internet" plug of the SR41 as a child of the WRT54G.

    How can i make it work ? when i plug it this way, i can't reach the router config page from my lan PC (but i see in tomato that the router is on.

    Thanks for any guidance.

    I've setup BEFSR41 as switch a while ago but it was with other WRT54G Linksys original firmware.
    If you disabled DHCP you also have to change ip to 192.168.0.X then use one of 1-4 ports to hook it up to tomato. Most likely you can't use WAN port.
    I'm sure there's other ways to do it.
    Hope it helps!

    that worked indeed, but when i plug a computer on the SR41, it goes to the internet without a problem, but it cannot see the other pc on my lan, connected to the WRT54G directly...

    how can i do ?

    Can you ping ether pc?
    All what I can think of is that computers are on the different subnet.
    What does ipconfig says on each computer?
