ppp connection problem

[Brian Henning]

Greetings all:

I am connecting to my isp with the following ppp.conf using the command
>ppp -auto isp
when i run the command i usually connect on the second try.
for some reason the connection drops after the first try, but my 
true problem is i can ping internal ips and not ips outside the network.
I think my problem is with my default route is not setup properly.

here is a snip of my ifconfig, for some reason i have two tun devices.
i think that is caused by trying to dial up twice? any thought on 
how to setup my default route properly?

Thanks,

brian
