A really odd issue that I (and a few others) can't work out...

I'll keep this simple - for a few months I was hosting online game servers without any issues at all, then people online stopped being able to see the servers I'm hosting - this is despite my copies of those same games being able to see other online servers without any issues at all.
All the ports appear to be forwarded correctly - and anything connected to my router (whether by cable or Wifi) can see my servers as well as online ones - but nobody outside the routers range can see any servers I host at all - even with a static IP address set up. I've even tried hosting the servers on 3 different systems with no change.
As you can gather it's got myself - and several others - completely puzzled.  There seemed to be no reason for the issue to come up randomly without warning and I was wondering if anyone had any suggestions that could solve this issue.

I take it nobody has a clue about any possible solutions then?

Good morning Hugh,
A warm welcome to the forums.
I'd suggest you give the community a bit of a chance here.  You posted late Sunday afternoon and only 15 hours have passed since you posted your question.  It is not a generic issue and might be better placed in the games forum.  I've asked the mods to consider moving it.

Nice to see that I'm not the only one!
I started having this issue about three months ago, possibly a month or two before; I'm not sure.
I was hosting a game server and all was working perfectly, then one day, it decided not to show up in the list to my friends (outside my connection). I hadn't changed anything so I couldn't figure out why. Restarting computers and routers had no effect so I was baffled.
I've just moved the servers to another address (both are on Plusnet Fibre) and all was working fine an hour ago. I tried port forwarding a new port but it wouldn't work - so I restarted the router and now no ports are forwarded correctly.
This is a major inconvenience as I use my internet connection to host a lot of services for myself, family and friends to use and it's a real nuisance when none of it works!!!
Note: I just phoned Plusnet about the issue as soon as I got it and was immediately advised that they cannot support me and that I should go to the Community Forum.

So are you both using the plusnet supplied routers? Perhaps they are not the best (I gave up using the technicolor).
I assume these game servers are  are on  windows - maybe its firewall plus updates "changing things" could add to the confusion.

wonder if it's related to udp blocking that seems to have arrived, though that could be me making stuff up - but might be worth looking at

Has the Plusnet kiddies firewall some how been switched on? Worth looking in the Member Centre Portal just in case.

What is this UDP blocking?

Is there any possibility of this being related to one of the acquired IP address groups resulting in someone's out of date geo-location database believing that these hosts are not in the UK?
Such a thought could be 'marbles' - but potentially relevant.
@Hugh & Jencox
Can you look at your current IP addresses and post the first 3 octets here please?

Re: A really odd issue that I (and a few others) can't work out...

The external IP address is 212.159.116.XXX  (Naturally I've covered the last 3 digits)
The first time I contacted Plusnet about this they suggested that it was happening because I lacked a static IP (which may explain one of the server programs, but the other one auto-updates any changes on the global server list)
With what Jencox has said, I did notice a major downturn in people getting onto my servers around that same time - but I had put it down to people being on less often during the summer holiday period.  
The router I'm on is the standard Technicolor TG582n.  Sadly I can't adjust its firewall under the admin login (I get an "This level is protected and not editable" response) - but I have enabled "Game Mode" - and opened the ports relevant to the game servers - with no change on people being able to see them.  All 3 systems programs are indeed under windows - and have been tried on 2 different systems running XP SP3 and a third running Win7 (starter edition)
If it is indeed the router that's causing this, I would like some suggestions for relatively cheap ones that can handle the job.
