Greets: I have two SuSE boxes, one 10.1 (with internet connection) and one 10.3 connected to a second private NIC (eth1). I've done the following: #echo "1" /proc/sys/net/ipv4/ip_forward # iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE # iptables -A FORWARD -i eth0 -o eth1 -m state --state RELATED,ESTABLISHED -j ACCEPT # iptables -A FORWARD -i eth1 -o eth0 -j ACCEPT And on client machine added default GW. Eth0 would be external interface and eth1 private. It looks like an issue with firewall not allowing or forwarding packets correctly, doing a: # tcpdump -i eth1 icmp While running a ping from client machine and it was received properly. -- Best regards, Nick Zeljkovic -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
