Yes.  I am confused, since it should work.  Check the /etc/pppd/ip-up
file.  You can grab the DNS values using the script.  Also, pppd 
sometimes refers to /etc/ppp/resolv.conf.  See if it is setup properly.

It should be!

During the ppp connection, pppd will setup the default gateway based
on what the server tells it to do.  Check your route table during
the connection.  You can manipulate it with the /etc/ppp/ip-up and
/etc/ppp/ip-down script.  The default scripts should work seamlessly
though.
