Hide Forgot
In my case I have configered my laptop for a LAN with a router (which is my default gateway) for when I'm at my office, and a dialup PPP connection via /dev/ttyS0 and my ISDN adapter to my ISP for when I'm elswhere e.g. at home. When no LAN was configured PPP was fine. Since my LAN was configured (with a default gateway) PPP gave me a connection that wouldn't work. Debug told me PPP could not change the default gateway (although this option was used). I found that this is solved by placing the call to pppd in a wrapper script that does a 'route del -net 0.0.0.0 gw router-ip' before calling pppd, and a 'route add default gw router-ip' after disconnecting and stopping pppd. With de default gateway on eth0 out of the way, pppd is able to establish the PPP peer as default gateway. I don't know if this is a bug or a feature (or a user error), but this behaviour (if a feature) might be doumented e.g. in the ppp-faq. There is already another problem report on default gateways & ppp, with another cause. Regards, Rob
