According to the postings in the last time to ssh, I'll assume you have 
something wrong with your dns setup.

Unless you are running your own nameserver I would add this to 
/etc/ppp/ppp.conf

enable dns

Further more check your /etc/hosts to see if there are all internal 
computers listed, so that the dns not tries to resolve internal 
addresses. Also make sure /etc/resolv.conf contains "lookup file bind".

If all this doesn't help you may (but don't judge me for that if it 
doesn't make sense) add to /etc/ppp/ppp.linkup

  ! sh "route delete default"

or
! sh "route flush"

Hope that helps
