Remove it, you don't need it.

You don't need to ifconfig tun0, the ppp daemon will do it for you.
Remove tun0 from the network_interfaces list, and the ifconfig_tun0 line.

Edit /etc/ppp/ppp.linkup to look like mine:

#
# In all cases (since we've only got one) add his address as default
# gateway.  This has the added benefit of making *any* packet routed
# off our network redial the link.  Of course, this makes casual
# name lookups expensive.
#
MYADDR:
 delete 0 0
 add 0 0 HISADDR

This will remove the default route and add 'his' address as the
default route each time the PPP link comes up.

tun0 configured as localhost?  Two configuration lines for lo0?  I'm
not sure what is happening, exactly, but I know it is very bad.  ;^)

Try cleaning up the configuration as suggested above.  If that doesn't
work, e-mail me back and I'll send over my configuration, with
passwords removed.  Works every time.  ;^)
