I don't know yet if my ISP is blocking any ports. I've received a few
hours ago a very general and ambiguous response, so I will have to call
them to speak with technical staff.

As for the dynamic public IP address, I solve that bit with the free
service provided by http://freedns.afraid.org/ plus a cron job for
updating the public IP address every certain amount of time that you can
define. There also are clients to do that, like Inadyn.
