Setting Up 2 i.p address on one computer with one ethernet card


Hi i have 2 separate i.p address and i am looking to route traffic through each of them (load balancing). But for the life of me i cannot get it to work.
Is it possible on 1 ethernet card? To set up two separate i.p addresses?
The two separate i.p addresses are using the same gateway.

Thanks much

Yes I am trying to set up my linux box to accept data packet over 2 separate i.p's and load balance between the two... Both i.p use the same gateway server ex(10.144.0.1) but I cannot bind two i.p to one eth0 card

Heres a copy of my ifconfig


eth0 Link encap:Ethernet HWaddr 00:50:BF:9781
inet addr:209.105.221.138 Bcast:255.255.255.255 Mask:255.255.255.0

But as it stands i own the i.p address 209.105.221.138 and 209.105.221.210 and want this box to accept packets over both and send packets over both i.p's and help would be much appreciated

i am using iproute2

Tell me if this means that it is working and if so how do i go about checking if it does in fact work?
