Niels, I do not think the two nics are your problem. First off you will need two things. The first is patches made by Julian Anastasov, I had a link but it does not seem to work. Julian subscribes to this list so maybe he will post an updated link to where they can be found. After you apply the patches the Linux machine will need to be running NAT in some manor. Because I have routers on each of my DSL lines I perform two rounds of NAT or PAT. One in each router, and then again in the Linux router. Without those two things, I was not able to get things to work by using only the example on lartc.org that you posted below. You will also want to dial in your DNS to servers for each IP block, and load balance that as well. In doing the NAT/PAT you will need to give the outgoing interface each of the IP's that your routers will be translating to. Example. Public IP - Router Nat to say 10.1.0.3 On the Linux router your interface may have 10.1.0.1 as the ip, so you will need to add the other ip as well. ip addr add 10.1.0.1/16 brd 10.1.255.255 dev eth1 ip addr add 10.1.0.3/16 brd 10.1.255.255 dev eth1 You will need to do that for each IP that the routers will NAT/PAT the public ips to. Then in the Linux box, you can map those IP to what ever internal ones you want from there via NAT or PAT. Hope that makes sense and helps. On Wed, 2002-07-31 at 06:42, niels@wxn.nl wrote: > Hi ...
