Subject: [B.A.T.M.A.N.] gateway-tunnel crashes with multiple net-dev
Date: Sat, 17 Nov 2007 16:40:55 +0100 [thread overview]
Message-ID: <473F0B87.9050002@leipzig.freifunk.net> (raw)
Its me again... ;)
At first i thought this is a problem with our complex setup on the
freifunk-routers with olsr+batman on alias-interfaces and so on, but
know i testet batman on my Laptop and have the same problems with
multiple network interfaces and gateway-tunnels.
I dont know how this gateway-tunnels really works, but i think this
pseudo-NAT on gate0 not really works or send wrong source-IP or what else...
Regards
tetzlav
