I run a cron job on my internal network that sends a request every 10
minutes to a cgi program that sits on my public web server. The cgi program
does some authenticication, and then sticks the value of $ENV{REMOTE_HOST}
in a DB_File. This works because the router makes the request, so
$ENV{REMOTE_HOST} is populated with my router's dynamically assigned ip
address.
I then have a redirector cgi program that sits on my public web server that
redirects to my router. So http://my.public.site.com/redirector.cgi
redirects my browser to the router, which handles the port forwarding.
This way, I always have access to my current dynamic ip address. Unless, of
course, it changes and the cron job hasnt run ret, which has happened.
The other suggestions are just as good, but as always TMTOWTDI.
