Joe - Linux can do this, check out: http://www.lartc.org/ More specifically: http://www.lartc.org/howto/lartc.rpdb.multiple-links.html and http://www.ssi.bg/~ja/#routes I am working on a redhat project that requires QoS over multiple VLAN's. I was reading up on tc and imq devices when I came across this information. Haven't tried this config, but it look like it should do what you want.

We have a remote office that can only get 768Kbps DSL, which they've not totally maxed out. So management's solution now is to buy a second DSL line, but they won't let me buy a dual WAN router (in case they add a 3rd DSL line). I've found some great articles on how to get the interfaces working with 2 default gateways (I used this: http://www.linuxquestions.org/linux/answers/Networking/Spanning_Multiple _DSL s) and that is all running fine. It alternates every few minutes which WAN port is used when I traceroute yahoo.com (which is fine) and everything is connecting fine from the router. However, I can't figure out how to get NAT running on the server for the 2 WAN ports for clients inside the LAN. I can NAT to 1 DSL, but that is useless. What I am looking for is a tutorial in how to do this or a pointer to someone who can help. Anyone know of a resource for this? Joe Johnson joe () sendjoeanemail com
