HI all, I have an internet connection on eth0 (10.0.0.1) and a private network connection on eth1 (192.168.0.1). I put the masquerade configuration on a kernel 2.4.4 : iptables -t nat -s 192.168.0.0/24 -o ppp0 -j MASQUERADE echo 1>/proc/sys/net/ipv4/ip_forward A workstation on my network succeeded to ping both eth0 and eth1, but didn't succeed to go out of my network to reach the internet. Anyone can help me ? Best regards
