Greetings,

I have had a problem where the default route when diald establishes a
modem connection. To get my connections to work at all, I use an "ip-up"
script that sleeps for 5 seconds, then runs "route add default ppp0".
This is a pretty ugly approach, because the packet queue gets dumped as
soon as the link comes up, and there is a period of a few seconds where
network connections will fail. This problem has persisted through old
(0.16.5) and new (0.98, 0.99) versions of diald, and a few versions of
the 2.2 kernel. I've included a lot of information below, including the
diald log, diald.options file, system info, and routing tables. Any
ideas on how to fix this?

Thanks,

Ben
