Using VNC through the Internet

You shouldn't get a different message when connecting by IP to connecting by
DynDNS, unless your DynDNS settings are wrong. Do an "nslookup
<my_dyndnsname>" where <my_dyndnsname> is the DynDNS machine name you have
chosen, and check that it gives the same IP address that you have been
As regards "Connection refused", that means that the IP address you gave
refers to a live machine, but that that machine isn't accepting connections
on the specified port, in this case the VNC port.
>From your mail, I'd say that the problem is that you have remoted port 5800
but not port 5900. You don't need to enable UDP on those ports for VNC to
work. Also note that if you use VNC over the Internet, you may prefer to
buy a copy of VNC Enterprise or Personal Edition (Personal is the cheaper,
designed for home use, but is not yet released. :( ), which take care of
security & encryption of the VNC session.
