Of course you can. *Linux is designed to handle multiple networks
(really any OS is, but...).
The caveat being that the networks need to be different IP subnets. *You
can't have both networks in the '192.168.0.X' range. *(Well you can, but
for simplcity's sake, let's not.)
If one network is 192.168.1.X and the other is 192.168.2.X, then you
shouldn't have any trouble routing between them.
I guess the main question here is which one will be the default gateway
to the internet? *I would make the 'wired' one the default for internet
traffic, then if that goes down, you can have all internet traffic fail
over to the modem (using a higher preference) if you want.
Make sense?
Hi:
thanks for your help.
The ubuntu will automatically change the connection when I plug usb modem or RJ45.
That means, if I originally use usb modem connect to the Internet then plug in the wire line, Ubuntu will run autoeth0 and my usb modem will disconnect.
I previously uss ubuntu 7.10, which is not as nice as 8.10, and use vodafine usbmodem driver to connect to the internet.
I can use 2 networks without changing the ip address, one is assigned by ISP and another is set by myself, 192.168.1.100.
So, I have to manually configure the ip to make them under the same domain?
appreciate your help,
sofian
