Re: Multi WAN Routing



It sounds like what you're looking for is Policy Based Routing (PBR). The LARTC howto link you mentioned below is actually what I did when I setup a Linux laptop with a trunk interface connected to several different VLANs that I needed to route between.

Hallo,

i will try a Multi-WAN-Routing.

It look like:

LAN -- Router (Debian squeeze) -- ISP Line 1
 |----- ISP Line 2

The ISP- Ip's are static.

Here some links i have found:

At the moment my routing table looks like:
rtr-0002:/var/log# route -n

At the moment I use ppp (pon/poff) dail up.
Not clear thinks are:

- how do 2 PPPoE connections at the same time?
- where do I place the code for multiple routing
 (ip route add default scope global nexthop via 1.0.0.2 dev eth1
weight 1 nexthop via 2.0.0.2 eth2 weight 1)
- did this setup runing with SSL or SSH connections? (while the
connection is keep alive they must use the same route i think?)

Thanks,
regards Basti
