At the moment I have a small LAN connected to a Linux server. The linux
server provides internet access for the LAN by means of a cable modem. I
therefore have a dynamically assigned IP address. I want to be able to
access certains services such as SSH from outside and in order to manage
this it would be easier to use dynamic dns rather then having to phone up
to find out what the current IP address of the server is.
At the moment howerver I run a DNS server for the LAN on the linux box.
It's primary function is to provide a chaching DNS service to the LAN but
it also has a zone for the LAN in which it is the master DNS. Since this
zone is not externally accessable, it is just a domain name I made up. What
changes will I need to make to this setup if I get a proper internet
accessable domain name for the server using dynamic DNS
