Where do you get the impression that dyndns.org is a port redirection
service?  I'm a lifetime member grandfathered in from when I joined
about a year after Monolith (ml.org) went away.  Correct me if I'm
wrong, but dyndns.org has never been in the port redirection business.
Pfft, as if it's even possible to be in the port redirection business
to start with without being your ISP...
