I've just started to recently look at CBQ and HTB, but I've been wondering whether or not something like the following is possible: I've got two external links: +--+ | |-----ISP1 |FW| | |-----ISP2 +--+ One link has a bandwidth cap, and the other doesn't. What I want to do is, punt all outbound traffic out via ISP1 (free), but if it's outbound capacity becomes full, start directing subsequent connections out via ISP2. This way ISP2 is only used when ISP1 is busy. I have no idea whether this is possible using 2.4 and advanced routing features. Or, whether it's just a stupid idea. Anyone? -- Adrian Chung (adrian at enfusion-group dot com) http://www.enfusion-group.com/~adrian GPG Fingerprint: C620 C8EA 86BA 79CC 384C E7BE A10C 353B 919D 1A17 [toad.enfusion-group.com] up 8 days, 14:07, 17 users
