Port forwarding with UPC Technicolour router

Hi all, felt it was the best place to get some help.

I recently signed up to UPC in the new house and received a new technicolour router, believe its a TC7200 model or someting along those lines


Pretty simply question, why or how can I open ports on this router?

I've got into the admin panel and got to forwarding, and assigned the ports I want to open but nothing seems to be happening.

I have VNC server and DYNDNS setup on my laptop. I want to be able to access it from outside the house network. Just VNC access would be enough even, but with DYNDNS it would be handier to remember the address.

I also have sickbeard, sabnzbd and couchpotato running on various ports, again, cant get a connection to them outside the network after forwarding ports.

Any help would be greatly appreciated, portforward.com unfortunately had nothing to assist.

Thanks,
