Sorry, not sure if I am understanding what you are looking for?But you could try the following.You either need to set up your own DNS serer(s) (or edit LMHOST file as suggested on all computers) or subscirbe to Dynamic DNS service at places like Dyn....
When is this planned to be happening?I was very surprised when I discovered that this was not standard when I bought the router, I thought this was standard more than 10 years ago.RegardsCarl
