Hi, I'm wondering whether my problem can be solved with netfilter/iptables or there's any simple solution. This problem looks very simple, but I couldn't find a solution yet. I'm configuring an wireless ad-hoc network with three laptops; A ---- B ---- C where A and C can only talk to B, and B can talk to both A and C. A and C cannot talk to each other. I'd like to configure B so that A can talk to C via B (and vice versa). The addresses are, A: 192.168.0.1 B: 192.168.0.2 C: 192.168.0.3 Since this is an wireless ad-hoc network, every machine has only one (wireless) interface, so B should receive a packet through its interface eth0 and forward it through eth0 again. Currently, A, B, and C only have the same basic routing table; Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 192.168.0.0 * 255.255.255.0 U 0 0 0 eth0 169.254.0.0 * 255.255.0.0 U 0 0 0 eth0 127.0.0.0 * 255.0.0.0 U 0 0 0 lo B cannot forward packets with this routing table. Can I use netfilter/iptables to make this network work? or is there any solution? Thanks, Steve
