Hi again,

I'm currently testing with a few openwrt boards - generally its going well
and I'm connected to the Internet via a BATMAN node thats talking to a
gateway node - pretty good stuff.

I've noticed something.  On my (non gateway) node the traffic is going out
the "gate0" tunnel NIC.  My notebook is connected wirelessly to an [V]AP
on the node so I need to have a MASQUERADE rule on the gate0 NIC to allow
my local AP subnet (192.168.100.0/24) Internet access.

In a live network, with lots of nodes, will there still only ever be one
gateX NIC ? - is it enough to just have an "iptables -t nat -A POSTROUTING
-o gate0 -j MASQUERADE" rule ?

thanks very much for all the help

Derek
