Hello. I am a network newbie trying to set up a linux machine so it will periodically establish ppp-connections through a modem and perform some performance tests on these connections without the rest of the traffic on that machine being affected. How can I set up routing so that a certain user/program on the machine uses the PPP dialup connection while the rest of the system (httpd, network monitoring stuff) uses the network''s internet gateway? I think this is similar to the example with the two cable modems in the HOWTO, but I can''t identify my ''John'' by the source IP... thanks, Christian Henz.
