Re: PPP link kills routing table
I have had the same problem, I think, for some time. After
connecting to my isp's dialup with ppp route will just hang
as Mark mentioned. I have just merrily ignored it and manually
typed 'route add -net default ppp0' and then it works. Not a
big inconvienence, but I have been curious why this happens.
I do have defaultroute in my /etc/ppp/options.
