Hmm, that seemed to do the 'routing' trick for sure. *MUCH* better than having to futz with the routing. However, I don't know what's happening with the link getting all balled up, since I'm not sure whose fault it is.
The rationale behind the ppp.linkup bit is that ppp doesn't know where your default route should point 'till it negotiates an IP with the other side.
So why doesn't it wait to se the default route until after it knows the other side? It seems silly to set something that you know ahead of time is bous.
Cause otherwise it won't get the packets to start it dialling, and it doesn't get any new default route. Catch 22.
I like to use an interface route for the dial-on-demand case, but that only work satisfactory when you are not doing FTP or other address-encoding protocols locally from that box, and you _are_ using aliasing.
I can go into the details for the above if there is interest; I've already described my code to Brian (and offered him a copy of the code, IIRC).
I didn't know you had anything working in this area. I added the interface route capability to ppp (add default INTERFACE) but you still need to configure the interface before using that route. The only way to defeat this problem is with libalias support - it's still on my list of things to do.
