    Hi all,
    I got 2 WRT54 routers in order to link to sites together.
    The problem I'm having is the computers from site A don't "see/ping" the computers on site B and site B doesn't see site A.
    Can it be setup so that the computers from both sites can "see/ping" all the computers connected?
    If so how can I do that?
    Also note that at this stage Internet access is not required, however ADSL should be installed in about a month or so.
    Would I need a firmware upgrade to do so?
    How do I setup the routers so that each site can see all of the computers?

    Router: WRT54GL
    Firmware: 4.30.0 OEM

    Site A: 3 PC's on copper, 1 PC on Wifi.
    Router IP: 192.168.1.1
    Router Subnet: 255.255.255.224

    Site B: 2 PC's on copper, 0 PCs on Wifi.
    Router IP: 192.168.2.1
    Router Subnet: 255.255.255.240


    Many thx in adv.

    You have the two sites on different subnets, and that is why the cannot see each other. They all must bd on the 192.168.1.X or 192.168.2.X subnet. If you are using the DHCP servers on both sites make sure the IP address ranges do not overlap and the the local addresses of both routers are different,

    how are they connected to each other?
    they dont have to be on the same ip subnet, but it can make things easier.
    if you want them to stay on seperate subnets like they are, youll need to add some static routes to each router so that the machines know how to talk to the other subnet.
    if you can give a bit more information on how they are physically connected i can try to suggest some routes for you.

    i'd say go with the static routes and different subnets if you would like them to appear as completely seperate networks.

    If you want to keep the existing subnets for Net A and B, just telnet into the router that is in "client mode" and issue the following command:


    # echo 1 > /proc/sys/net/ipv4/conf/`route | grep default | awk '{print $NF}'`/proxy_arp

    [Edit]
    For this to become permanent after a router reboot, you'll have to enter these commands into the routers startup script.

    #nvram set rc_startup="echo 1 > /proc/sys/net/ipv4/conf/`route | grep default | awk '{print $NF}'`/proxy_arp"
    #nvram commit
