Windows 7: Unknown UPnP port

10 Dec 2009   #21

Windows 7 Ultimate x64

Hi Damob,

I'm glad you've managed to prevent the issue by disabling SSDP, however we haven't found the route cause. I still have my suspicions it's to do with Teredo.
You can disable teredo using the netsh command:

set state disabled

If you set that and then start the SSDP service does the issue persist? If not then I think we found the culprit.

Windows Seven 64bit build 7600

Hi There DC187,

Well here's the funny thing I have restarted both services and rebooted, and low and behold .. nothing , zilch nada is popping up on the router now !!

The only thing that I have done since last night is to disable homegroups and remove the libraries from explorer, so the two services for homegroups are disable atm.

I will re enable those 2 services either later on tonight or tomorrow morning. (right now I have a humongous piece of steak that is begging me you cook it

I will update later , not on the steak tho, you probably don't want to know/care !!

Cheers chap.

Windows Seven 64bit build 7600

Update :

Ahh that was a pucker steak, on a bed of rocket salad, new potatoes and a side of Lincolnshire sausages.. Yummy. I would have saved you a bit DC but I couldn't figure out how to get it through UPnP and past my firewall :P

Oh and other news...

Re enabled everything : homegroup discovery and listening services, SSDP (I haven't re activated the homegroup and joined it as I don't want to go through setting up my folder permission again)

And so far there are no ports being opened on my router via UPnP, so what ever it was it doesn't seem to be coming back.
I will monitor it for a day and see what happens.

I think you could be onto something regarding teredo, but at this rate we will never know !

Cheers again

Hey there. I think I should post it here because it's a Network issue. I want to turn on the UPnP because I want to host games in MW2. So any hints how to do it? I was searching the whole morning in settings but nothing. Thanks in advance.

Opening an UPnP port on windows startup
Hello fellow 7ians Just wondered if there's a way to open 2 ports via UPnP (specifically 113 and 3389) on startup, as my silly router refuses to give my computer the same IP every time. Yes, I know I could set my IP as static locally, however, I move my computer to various locations to "share"...
