How To Use Two Network Interfaces Simultaneously ?

Hi everybody,

I'm using Opensuse 10.3 with KDE 3.5 and my computer has two network interfaces: a wireless and a wired. I'm using the wired card to access the Internet, and the wireless for a local network with a PC104. I have to switch to the wired card each time I need to search some information. I using KnetworkManager 0.2 for this.

Is possible to have the two networks working simultaneously ?. How can I do that ?.


Thanks.

Yes, sure.
You should make sure your default route for internet and then modify your route table for internet and local by route command.
Below is my example:

#route -n
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
192.168.2.0 0.0.0.0 255.255.255.0 U 0 0 0 eth1
192.168.234.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0
10.244.4.0 192.168.234.254 255.255.255.0 UG 0 0 0 eth0 -- for local
169.254.0.0 0.0.0.0 255.255.0.0 U 0 0 0 eth0
127.0.0.0 0.0.0.0 255.0.0.0 U 0 0 0 lo
0.0.0.0 192.168.2.254 0.0.0.0 UG 0 0 0 eth1 -- for internet

and then check your /etc/resolv.conf

nameserver 10.244.4.1 --- for local
nameserver 168.95.1.1 --- for internet
