    I have a strange (to me) problem with my home network consisting of a
    Linksys DSL router, a Linux server/router and two Linux end points (one
    laptop and an embedded linux device). My current topology is:

    Internet/DSL modem
    |
    Linksys
    (192.168.1.1 w/ static route to 192.168.0.0/24 via 192.168.1.17)
    |
    wifi--(192.168.1.101 DHCP) Redhat 9 Laptop
    |
    (192.168.1.17/24 default gw 192.168.1.1)
    Redhat 7.2 Linux Server/Router (kernel 2.4.21)
    (192.168.0.1/24 )
    |
    Ethernet
    |
    (192.168.0.90/24 gw 192.168.0.1)
    embedded linux (kernel 2.4.19)

    The laptop and the embedded device can ping the internet and resolve
    addresses.

    ifconfig shows all interfaces are up and with ip-addresses and
    netmasks, etc.

    The router/servers ip_tables is flushed with ACCEPT policies.

    The router/server /proc/sys/net/ipv4/ip_forward is 1.

    I can not make the server/router route traffic between the laptop and
    the embedded device. I know that it's not the optimal topology but at
    this point it's the possible way. Optimally I want to have the
    server/router on a Linksys ethernet port rather than on the wifi side.

    I've been trying all kinds of configurations for the routing tables
    (using route and/or iproute2) but nothing seems to work. Am I missing
    something fundamental here?

    Thanks
    Ronnie Pettersson
