    Greetings,

    I am running FC3 x86_64 on a DSL-connected pc, which works great by
    itself; I have another machine running windoze XP, and would like to
    use the first pc as a gateway, so that windoze can have access to the
    network.

    In the linux machine, with 2 ethernet devices, eth0-> connected to
    windoze, eth1-> connected to the ADSL modem (under ppp0), eth0 is set
    with ip address 192.168.1.1, netmask 255.255.255.0, and eth1 is set by
    adsl-setup... The windoze pc has an ip address 192.168.1.2, netmask
    255.255.255.0, gateway 192.168.1.1 ( = the FC3 ip address).

    Using this setup, windoze can ping linux, but linux can't ping windoze
    (no response). I even tried running ping with -I eth0 with no luck :(

    Well, i started doing the usual stuff in order to set the gateway under fedora:
    1) enabling ip_forwarding on /etc/sysctl.conf
    2) modprobing iptables_nat
    3) adding iptables masquerading rules to table nat (iptables -t nat -A
    POSTROUTING -o ppp0 -j MASQUERADE)

    needless to say that windoze remains unconnected... what am I missing????
    Thanks in advance
