Thanks, I figured it out sometime ago and i am using the DDNS from D-link mostly for all servers;
the FTP use the same DDNS, no problem
for the HP, same DDNS or the one from TZO (Both works)
for the IP camera, I add the port number to the DDNS..
for my Fire Fly streaming, I add the port number to the DDNS as well.
so everything is solved ... thanks again
