Lync Federation Traffic

Hi Guys,

 

Recently we've configured Lync 2013 on our network.

 

What i've noticed on the PA external firewall is the Lync federation traffic from the internal lync clients to for example 'Skype clients' on the web or other organizations is classified on the PA as 'unknown-tcp'... on port 443.

 

Currently i've got a security policy purely allowing 'unknown-tcp' on port 443... but this isn't all that secure.

 

Is there a workaround for this? or is this apart of lync that Palo Alto haven't developed an App-ID for yet?

 

Cheers,

Brad
