Today I spent the best part of the morning to configure a SLES 10 SP2 server as a simple router. I googled quite a lot and could not find a nice and concise post on how to configure SLES 10 as a simple router, so I thought I’ll write up my experiences in the hopes that it will help someone. Although this was done on SLES 10 I am pretty sure it will apply to openSUSE as well.
My setup is as follows: Local lan is 192.168.0.0/24 and I want a private lan on 192.168.1.0/24 so that I can run stuff like DHCP and PXE without upsetting everyone on the network. I have a SLES 10 server with 2 network cards: eth1 connected to the local lan and eth0 connected to my private switch. The local lan is connected via ADSL to the Internet and I need my private network to also be able to connect to the Internet.
