Re: Problem setting (new) default route with pppd after connecting
This is normal behavior from my experience. I've never seen
PPP replace a default route that already exists. If you only
have a few known hosts or networks at the ISP you could build
a script to inject those host and net routes into the table
when PPP comes up. I've done this with PPTP. If you'd like to
see my script I'll share. It shouldn't require much change to
work for you.
