Always use eth0 for xbmc

[Roy Terhaar]

Hi,

Situation:
-----------
I have a setup where I'm trying to use both eth0 and wlan0 network interfaces.
- eth0 (192.168.1.15) will be used for xbmc and has internet connection via router 192.168.1.1
- wlan0 (192.168.2.10) will be used for something else, has no internet connection via 192.168.2.1
Both interfaces can ping to their individual routers, so far so good, on a network level everything seems to be ok.

Now the problem.
--------------------
Once wlan0 is enabled, xbmc 'automatically' selects wlan0 as the interface to be used as some sort of default behavour.
What I want is to use eth0 for xbmc regardless of whatever happens to wlan0.
If I bring wlan0 down using ifdown, xbmc switches back to using eth0 which is what I want, but it also means I can not use wlan0 anymore.
If I enable wlan0 using ifup, xbmc switches back to using wlan0 interface.

Questions:
------------
- how can I force xbmc to always use eth0 (while wlan0 is enabled)?
- how can I configure that so that it also happens at boot time?
