Greetings all, I was trying to set up a NAT, the topology of this network is: DEVICE <-----ad-hoc-----> BOX wlan0 <------------> BOX ppp0 <--------------> Internet The ppp0 interface is set up with PPPoE by eth0, and my iptables rules are: *filter :INPUT ACCEPT [31316:22057491] :FORWARD ACCEPT [139:8687] :OUTPUT ACCEPT [30478:19500665] COMMIT # Completed on Thu Jan 22 12:06:57 2009 # Generated by iptables-save v1.4.2 on Thu Jan 22 12:06:57 2009 *nat :PREROUTING ACCEPT [3067:206779] :POSTROUTING ACCEPT [37:2234] :OUTPUT ACCEPT [436:43436] -A POSTROUTING -o ppp0 -j MASQUERADE COMMIT # cat /proc/sys/net/ipv4/ip_forward 1 By using wireshark, I can sniff TCP SYN requests from DEVICE are going through ppp0 correctly but the response was never forward to wlan0. Could anyone help? Thanks!
