My router dishes out local IP addresses, the normal 192.168… stuff and my server has a fixed IP in this range. Now I want take advantage of the “multi-homing” (that’s what Netgear calls it) feature of my router so now it has two gateway IP addresses. The normal private one (192…) and a public one (24.12…).
On my OpenSuSE (version 11.4) under “Additional Addresses” I put a public IP in this new range (I have a few static IP’s to play with in the 24.12… range) and here’s where I am unsure.
My question is: Is this all I have to do? It seems to me that it would also be advantageous to enter the router’s 24.12… IP address into the network settings as well however I am not sure where to do that… obviously there can only be one default gateway under “Network Settings: Routing” but in a way the router’s 24.12… IP address would be the default gateway for a connection in that range and the 192… router IP address would be the default gateway address for connections in that range.
I know there are probably better ways to do things than give one networking card two IP addresses (especially since the server has two networking cards) in the long run but right now it’s the way I want to go as serves not only the purpose of a short term solution but also a learning exercise for me.
