How do you do this in web admin? I added an extra wireless interface because the built in one was not very stable, so I have 3 interfaces eth0 ath0 and wlan0. when i look in web admin it says I have 3 interfaces and tells be eth0 is my external interface and ath0 is internal, but there is no way to change these (I actually now want eth0 for internal and wlan0 for external.
(I ended up hacking the database as per the previous post, but am in the process of a rebuild so would rather avoid it next time around!!!)
The very first response to your thread lists a wiki page.... the very first thing it says on that wiki page is how to do this from the web admin...!!!
