I'm going to presume that the ppp link is working ok. you should be
able to verify this by ping'ing the palm.

Try pinging the palm from the machine directly connected. 
then try from the dns server, or some other machine, using your
machine as a router. I bet it won't work.

Is packet forwarding turned on?

what ip is your machine?

what routes exist in your next upstream router?

Do you have any firewall rules blocking packets?

tcpdump -i ppp0 

You will probably want to setup NAT so that the network doesn't have
to know that your machine is a router. simplifies things a whole
bunch.
