It sounds like both work for you, but not at the same time?

If you set them both to the same IP address, it won't work.   
Actually, it won't work if you set them to different IP addresses on  
the same subnet (as defined by their netmasks).

I think you are trying to get Linux to do something that it doesn't  
do.  Try setting them to different IP addresses, like 192.168.1.1 and  
192.168.2.1
