working with two nics (lan and wlan)

["H.S." <hs.samix@gmail.com>]

Hello,

I have a headless machine on my home network with a LAN card and a 
wireless card. If my lan cable is connected to its lan card, it gets an 
IP automatically from my firewall machine. But if I activate the 
wireless card, the networking seems to hang or freeze. My lan card is on 
192.168.0.x network and the wireless card is on 192.168.5.x network.

Is there any way I can have both the cards active and networking 
working? Perhaps by specifying somewhere which network has the higher 
priority? This is so because there are many situations where I sometimes 
want both cards up, mainly while trying out various wireless drivers 
with my wireless card. Another situation when I want to transfer huge 
amounts data via the wired network (higher speed) to other machines on 
the local network.

Alternatively, I suppose ifplugd can handle multiple cards at the same 
time. In my situations, can it be configured to use wlan card if it is 
up, else to use the lan card?

Thanks,
->HS
