Yes, that needs to be done locally so the router can router traffic to
the appropriate machine, but the issue I'm dealing with is when the ISP
doles out a new IP address for the router (with DSL that's usually every
router reboot, and for cable less frequently but often enough to make
depending on a given IP address impractical).

Just create a reservation in your DHCP server so that the server always gets
the same address.

Most of my servers have fixed IP addresses, but I'm about to add one to my home
where the IP will be dynamic.
The most common solution for making servers with dynamic IPs findable is DDNS,
and there are of course many free providers of such a service.
Put since this isn't a public server (just for testing and experimentation)
I'll be the only user, and it occurs to me I could take a few minutes to craft
a simple solution to know the server's current IP by using a CGI at one of my
sites hosted with real DNS in conjunction with an auto-run app on the server to
call it similar to what many DDNS services use.
I'm inclined to do that only because I like tinkering, but I thought I'd check
in here to see if this very specific use case was something others might have a
need for. If so, I might get around to documenting the CGI and sharing it, but
since most folks just use DDNS I'd guess this 302-based workaround is probably
too use-case specific to be of interest. If I'm wrong let me know and that'll
motivate me to get around to documenting it that much sooner.
