LYNC 2013 Edge SErver in DMZ with F5. Error connecting externally (www.testocsconnectivity.com)
I have deployed Lync 2013 edge server and it is in a DMZ with F5 BIG-IPs. I have used the Lync 2013 iApp. The reverse proxy 'appears' to be working (externally I can connect to my Front End External Web Service and get a challenge response: (https://webext.domain.com/abs)
The certificates have been installed on the Edge servers and F5 RP.
When I send out a 'Meet Now' request to my external user, they get page can't be displayed and I am tryingn to work out how to test where it is breaking down. Internally all this works fine.
I can telnet on 443 my two Edge Services; Access (sip.domain.com), Web Conf (webconf.domain.com) but not A/V (av.doman.com) Not sure how to test where it is breaking down? This is the OCS error:
Couldn't sign in. Error: Error Message: Unable to establish a connection.. Error Type: ConnectionFailureException.
