Although I have a range of IPs assigned for my DSL, I don't actually
use any other than 1 of them. My internal network has all private
addresses. I use masq to get out, and portforewarding for incomming
traffic to the web server or the ssh login host. The DNS is run inside
the network as well. I've loaded local zone records on the internal DNS
which ordinarily operates as a cache and foreward. My ISP has the real
zone records that everyone else uses to get at my boxes. Basicly, by
oveloading the DNS in this way, there is a seemless transition between
outside and inside addresses. I would be surprised if this sort of
arrangement wouldn't handle your needs as well.
