[Voyage-linux] bridge wlan eth [ 0.7.5 ]

[(spam-protected)]

Thanks Punky,

In this way, both the eth0 and the wlan0 are getting the IP address from the same DHCP, isn't it. 
Your solution works perfectly on IPv4.
The problem is that I need to assign to the wlan0 both an IPv4 and IPv6 address because the wifi has to work on IPv6.

When I add the following to the /etc/network/interfaces the br0 doesn't get an IPv4 anymore:

iface wlan0 inet6 static
address fec0::1:1
netmask 64

Any suggestion?

Cheers

Davide

I'm a bit confused regarding the bridge interface usage. In witch subnet it supposed to be? does it has to be in a separated one? I'm googoling but I haven't get it yet.
