Cannot Port Forward on O2 Wireless Box II

[JonnyGLC]

I've tried pretty much everything under the sun to try and get this router to actually forward the ports im telling it to, i've disabled intrusion detection and the routers firewall as well, yet my NAT type is still classed as Strict on games and if i use port checkers on the internet they say literally every port is still closed to incoming connections?!

I'm pretty much at the end of my tether with this now, anyone got any ideas?

Yep reset it 1000 times over, literally cannot get it to accept any incoming connections on any ports. Tried it on a couple of computers/laptops as well all with no firewalls etc.

Even the upnp doesn't help, it assigns the outgoing port fine but it just will not accept any incoming connections?!

Yup already done that, didn't affect it whatsoever!
