I've got this dream in mind: Work => Home
Uses the cable modem interface eth0 but only from syn packets coming from work (firewall at WORK blocks incoming connections) Home => Work Goes over a dialup connection to work over ppp0. How can I make it so only packets that are initiating from home => work start the ppp link and when that link is up all current work => home connections continue to use the eth0 interface instead of changing the routing table with a sledgehammer? If I could tell route to route only syn packets to work and existing ppp0 connections to stay on ppp0 I'd be very happy. Unfortunately I don't know how to do that. I've considered mapping a bogus internet unrouteable domain and masqerading all traffic to them with ipchains so the routing table could work by routing the bogus domain over ppp0 (but then does the firewall with ppp0 figure it out if it masqerades itself ?) This is a bit over my head with my current understanding of the tools I know. Does anyone have a better way? --mike
