I came up with a hack that has worked well for us. We have a frac-T1 line (12/24 ths) that is very reliable, but costs ~$600/month and only gets about 70KB/sec. We also have a connection from the local cable company; it's not terribly reliable, but it's only $40/month, and gets 460KB/sec. I setup squid proxy with the option "tcp outgoing address 12.x.x.x" where the address is that of the cable NIC. Then configured ipfw to forward any packets with the 12' address to the cable gateway. We get very fast proxied speed for web browsing, ftp, and other bulk transfers. But the regular traffic still goes over the T1 line. Sorta kludgy, but since I'm no routing expert, I was pleased with the results :) -Wayne
