The way I have set up DNSmasq in the past is to have it be the name server for the local network. If the query is for a machine on the local network, or one in its cache that has not expired, it handles it directly. If not, it passes the query to the upstream name servers it is configured to use. For dialup, you can configure the PPP connection not to update /etc/resolv.conf, only /etc/ppp/resolv.conf and have DNSmasq watch that file for changes. It will then use your ISP's name servers when you connect. I am sure you could do the same type of thing for a DHCP connection, so that it does not overwrite /etc/resolv.conf (PEERDNS=no), but updates another file that DNSmasq watches instead. Or you can configure DNSmasq to use specific name servers. On the other hand, if you need a name server with features that DNSmasq does not support, then you probably do not need DNSmasq running as well. You can just configure a local zone for your local network in Bind. The only time I can think of when you might want to run both is if you want one name server for the local network, and one that is accessable from the Internet. If the machine has separate interfaces, you can tell each program what interface to use. About the only time you would want to change the port would be if you are using a firewall to forward DNS queries from the INternet to a machine inside the firewall. In that case you would want to use a different port for BIND. But you are probably not going to want DNSmasq to query that name server as its upstream name server. One other thing to keep in mind - programs running on the local machine will use the name server pointed to by /etc/resolv.conf, even if you have a name server running on the local machine.
