Ex-BE now Sky - Thomson port forwarding issues.

I am a Sky customer forcibly moved over from BeUnlimited a few months ago. I still have a static IP.

I have a software system (for info: v2.sdrspace.com) that uses a server on port 7999 on a machine connected to my connection at home. I (try to) connect into my own server from work or other places.

The router is a Thomson 575 V7, software version 8.2.7.7

I have set up port forwarding on this port correctly and it always worked when I was with BeUnlmited.
Since my forced migration to Sky, my connection inbound no longer works. A port scan from a network utility website fails to even see the port on my router.

I tried disabling my router and PC firewalls to no avail.

Are Sky now blocking such inbound connections? Anything else I should be looking at?

I asked on Sky's own forums but didnt get a lot of response.

I've posted this in the Sky ISP section as well.. don't normally cross-post but someone who doesnt look at Sky forums won't see this and it may not be ISP specific...
