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????
