"I have a firewall running OpenSUSE 11.3 and dnsmasq." It is the dnsmasq
that is providing the info.
Yes, I know that a caching DNS server. My question is how does it know to give the local IP address for an external host name, when it's not configured anywhere in the box? Also, assuming it obtained it's external address from an earlier DNS request and matched it to the local address, I tried again this morning and it still knows. The cache shouldn't last anywhere near that long. The firewall has a different local network host name configured in Yast and also listed in /etc/hosts, which points to the local IPv4 address.
