This sort of thing is usually done with some sort of multi-port outbound NAT device that chooses the source interface to NAT from based on some "quality" metric it generates for the destination, and a state table it keeps for all the outside IPs. Products that do this include FatPipe, Radware Linkproof, and Mushroom networks. >-----Original Message----- >From: Charles Wyble [mailto:[email protected]] >Sent: Tuesday, November 04, 2008 12:32 PM >To: NANOG list >Subject: On the subject of multihoming > >I'm working on a small experiment which utilizes multiple outbound links >(in the experiments case multiple consumer 3G connections [to 2 Sprint/2 >Verizon/1 AT&T], Time Warner Cable Modem and an SBC Global DSL >connection. > >What is the best way to do outbound traffic engineering?
