[UAG] Minor issue when publishing Web Monitor of a DirectAccess gateway

When I deploy the Web Monitor of a Forefornt UAG acting as a DirectAccess gateway trough a Forefront UAG portal I was surprised to saw the error page as below:

After analysing the events on the Forefront UAG Web monitor we could see that it tries to access to unauthorized resources:

n order to apply a workaround, after publishing the Web Monitor go to the Trunk Configuration of the associated trunk:

On the URL Set tab you must have 32 WebMonitor rules, after the last one add these rules with Add Primary :

Name	Action	URL	Parameters	Methods
WebMonitor_Rule33	Accept	/(damonitoractivesessions|damonitorcurrentstatus |damonitoractivesessionsrefresh|damonitorcurrentstatusrefresh)\.asp	Ignore	GET,POST

Then Activate again the Forefront UAG configuration.
And after that, all working fine again.
