I currently are/am working on a mesh network that uses a wireless backhual for the mesh and a wireless card for client connectivity. The mesh side uses OLSR which is up and stable (no problems there). My problem/issue is that I do not know IPTABLES well enough to make my client side communicate on the mesh side. So in a nut shell. I have x number of clients per AP and all traffic needs to be able to pass back and fourth between both wireless interfaces (wlan0 and wlan1). ALSO the tricky one is the gateway node, It also uses an ethernet port (eth0).

Thanks in advance,
John

You might check out Arno's Iptables Firewall scripts. I use them and they work well. There are lots of plugins for different things. And he does respond on his mailing list when you can't figure out how to configure it.
