Hi people, I have two machines which are connected to iptables firewall. On firewall I have following rules iptables -A FORWARD -i eth0 -o eth1 -j ACCEPT iptables -A FORWARD -i eth1 -o eth0 -j ACCEPT echo 1 > /proc/sys/net/ipv4/ip_forward ( on firewall ) ip address of machineA is 192.168.1.2 ip address of machineB is 10.1.1.2 default gateway for machineA is 192.168.1.1 ( eth0 ) default gateway for machineB is 10.1.1.1 ( eth1 ) machineA -------- eth0(firewall)eth1----- -machineB I want make possible traffic flow from machineA to machineB. The above rules should do that, but because of something I cannot ping machineB from machineA. OS is debian. Any help is welcome. Regards Crux
