Hello all

(I am not subscribed. Please CC me)

Please forgive me if I have posed this message in the wrong place. I have
been searching for the answer for days with no resolve.

The question is:

How do I get eth0 and wlan0 both working together.

They are both using dhcp to the same simple network. That's right. Same
network. They both end up with gateway=192.168.0.1, netmask=255.255.255.0.
But ofcourse they do not have the same IP addresses.

I dont know if this matters but im using ISC's dhclient3.

This is what it looks like when wlan0 is brought up, followed by eth0.

i8600:~# iptables-save

So.
Is there a way to allow an application which has bound to wlan0
(192.168.0.202) and an application bound to eth0 (192.168.0.238) both have
access to the internet at the same time, and not require an application to
bind to a different local address?

Thanks

Jarne
