This has nothing to do with the fact that the rest of the world needs to
know your IP address to find your firewall.

We know this. However, most DDNS services require you to use their
domain. You tell the world to talk to:

www.HarryMotin.dynup.net

rather than:

www.HarryMotin.org

Note that dynup.net has a static IP. This kind of DDNS service is often
free. If you want to have the world talk to

www.HarryMotin.org

the DDNS provider can still be used, but they will have to provide a
static IP and do the packet forwarding for you. As I understand it, this
would be a pay for service.

No one ever said it was impossible. If you took our statements to mean
this, that was not what we intended you to understand. All we ever said
is everything is easier with a static IP. For example my current dialup
IP is:

209.178.191.21

If I brought up my local web server or FTP you could access it at this
address. All that's needed is for some way to publish the IP address so
others can know it. I know of some folks who set up an e-mail auto
responder for this similar to what's done for PGP keys. The return e-mail
would contain an IP address that could be used until it changed.
