This is the situation I have at home. I have my dedicated Linux box
serve DNS. When I connect over ppp, it could be to at least two
different networks, with different DNS servers. I modified the ip-up
scripts in /etc/ppp to update named.conf to put the DNS servers in the
forwarders section on named.conf and restart named.
Attached is the ip-up.local file I am using.
