Hello Jérémy ,

I have the same configuration and the same problem !!!
I found a solution (workaround ???) I activate the plugin : multiroute.... (with 50/50 weight)

And now the two external interfaces are working ...

Hi, i have two external interfaces :
EXT_IF="eth0 eth1"

each one having an IP on a different subnet :

the server runs debian/squeeze, with linux-image-2.6.32 (amd64).
If i start without arno-iptables-firewall, i can ping the server on both ip.
As soon as i launch arno-iptables-firewall, the server stops responding on eth0. I still can log in through eth1. From the server :
ping -I eth0 google.com
does not work, and
ping -I eth1 google.com

I tried configuring
or with
without success.

Is it a bug or misconfiguration ?
