Services - uPNP ?

Services - uPNP ?

Postby wernerapnj » Sun Oct 31, 2010 6:46 am

My router no longer appears in the Network map of Windows.
I have Network Discovery turned on.
When I scan for uPNP Device.
I have set Host Process for Windows Services to Enableall.
When I scan for uPNP devices the following notification appears:

Blocked event: |IPv4 UDP 192.168.1.1:1900(64566)|Host Process for Windows Services| Incoming

When I set WFC Mode to Enableall I still get the above Blocked event notification.

This is most frustrating !!!!

When a network negotiation is blocked by W7FC, W7FC specifies the blocking reason (i.e. the blocking zone/rule) precisely. No blocking reason specified - the block is made not by W7FC (W7FC shows all the blocking events regardless of the origin)
If HostProcess is blocked by W7FC you would see
.... Host Process for Windows Services| _TheBlockingReason_ Incoming
instead of
....Host Process for Windows Services| Incoming.

Most probably the block has been made by WindowsFirewall. For instance a policy to block all the incomings is used. Please check WidowsFirewall (with advanced security) settings.
Actually if you have several network filters sequentially, any filter can make decision to block and the decision is final.

That notification was copied from the W7FC log - It is not obvious that the message originated from WF. I would certainly suggest that you add functionality to specify the source of the notificatiom.

For example - adding "W7FC Blocking......." or "WF Blocking....." as part of the notification line and log entries.

I have turned off WF completely and my Router is again visible to the system. But now I am concerned since many of the default protections in WF are no longer active, and W7FC did not inherit them on start up.

Certainly some issues here that could use some investigation for the user interface.

That was short lived - my router has again diappeared from the network display.

And an application that I set for enableall is being blocked even though WF is completely turned off.

I'm beginning to think there are some 'bugs' in W7FC since its reporting a block on an app that should have complete access.

>I would certainly suggest that you add functionality to specify the source of the notification.

Done starting from 3.7

>I have turned off WF.

There are no requirements to switch WF off.
Most probably you should just tune WF accordingly.
To enable a network activity the activity must be not disabled at all the filtering layers.

>That was short lived - my router has again diappeared from the network display.

uPnP discovery is based on UDP, a protocol without delivery check.
So if the discovery message did not reach the router (of any reason), the response was not generated or the response did not reach the discoverer, the device will not be detected.
If so the detection will be scheduled for a next period (up to several minutes probably)
Did you see any blocked notifications?

>And an application that I set for enableall is being blocked even though WF is completely turned off.

The blocked details please. Turned off WF does not turn off all the related filtering rules.
WF (formally) is jus a control panel to WindowsFitleringPlatform (WFP, read the F.A.Q for the details). WFP is the integral part of the system, WFP is up, running and can not be switched off.

>I'm beginning to think there are some 'bugs' in W7FC since its reporting a block on an app that should have complete access.

So please specify the block. The blocking reason is declared precisely in the notification/log file.
