hey. im very new to linux so i will try and be as detailed as possible. My objective is to setup a simple router to do static routing between 3 subnets at my location and direct internet traffic to one isp controlled cisco router, and traffic to other work locations (on different subnets) to another isp controlled router. the computer i have set up has 4 network cards. i was planning on making 3 of them the routing card on each subnet, and the 4th is an ip that i have setup to have a direct connection to the internet. all are being read fine

now my first problem is that using the latest build of suse, i have been unable to configure all the ethernet cards to be activated at the same time using knetworkmanager and yast. enabling one card will just cause the other to be disabled.


now in addition to this, i have been unable to enable advanced routing in yast, with my static routes set up in it. on enabling with the tick box, and closing, the advanced routing i find has not enabled and the box is again unticked.

any help would be appreciated

to enable routing run "echo 1 > /proc/sys/net/ipv4/ip_forward" and then just add the routes on that you wish to route to, e.g. "route add -net 192.168.10.0/24 gw 192.168.0.1" to route traffic in the 192.168.10.0 network via the next hop of 192.168.0.1. i assume that your internet facing cisco router would be doing any source natting to RIPE addresses, so you wouldn't be looking into anything like masquarading on iptables at all. it's realy simple stuff to just route a few close networks, and if you wish to connect two machines who's default gateways are this one box on different subnets then there is no route even needed as the router in the middle just know s what is directly connected anyway.

thanks very much. i will give it a go
