How about the oposite problem: One LAN and two WAN Ports... What I really want is the ability to connect two LAN's across the internet using multiple ISP's for redundancy. Something similar to the following: <=><CableProvider><=> [PrivateLanA]<=>[RouterA] [RouterB]<=>[PrivateLanB] <=><ADSLProvider><=> Assuming Devil-Linux boxes as the routers how would/could you handle the routing? (Load balancing isn't my primary concern. I'm more interested in redundancy and uptime - but I'm sure others would be interested in the increased bandwidth possibilities) The next logical step is multihomed VPN's Any thoughts?

Hi, I think this should be possible by playing aroung with the routing tabl= e and the metric value. But this would work only for outgoing connections, because your IP addr= ess could change.

yes, it's included in DL... you only need the ip command and one of the = > 2.4.13 kernels: if the kernel configuration has the following enabled (think so, maybe = heiko could answer) CONFIG_IP_ADVANCED_ROUTER=3DY CONFIG_IP_MULTIPLE_TABLES=3DY CONFIG_IP_ROUTE_MULTIPATH=3DY need to use ip and tc commands in iproute to setup source routing ip rule add from x.x.x.x lookup 1 ip rule add 192.168.1.0/24 via 192.168.1.1 table 1 ip route add 0/0 via x.x.x.1 table 1 ip rule add from y.y.y.y lookup 2 ip rule add 192.168.1.0/24 via 192.168.1.1 table 2 ip route add 0/0 via x.x.x.1 table 2 and you can load balance on the output by ip route add default equalize nexthop via x.x.x.x dev eth1 nexthop via y.y.y.y dev eth2 There's more afterwards on checking the setup and configuring services, start-up scripts, for doing ha. this configuration will detect a dead = link by marking it 'dead' and will recover after some traffic has gone = through the internface (ping icmp).=20 Original post by: -=3DFrancois=3D- fm...@fm...

I suggest putting the Linux kernel .config file somewhere on the CD so everybody interested in the details can check if a specific feature is enabled or not. -- MfG / Regards Friedrich Lobenstock |

Assuming there is no network address translation, you can use FreeSwan... disted w/ DL (and widely used by Heiko) John --- Erik Christensen <eri...@ki...> wrote: > How about the oposite problem: One LAN and two WAN Ports... > > What I really want is the ability to connect two LAN's across the internet > using multiple ISP's for redundancy.
