OCS 2007 R2 Edge

We have three edge servers all with co-located services (as recommended per MSFT docs). I believe I need a 'web conferencing', 'AV', 'SIP' and 'Edge Internal Interface' virtual server on the BIG-IP's which then dispurse to each respective interface on each Edge server. My question to all is, should these all be SNAT Auto Map? All my addresses I used on the Edge Servers are publicly routable.

 

 

I am currently experiencing a problem where when a user is going through the Edge server to connect to a live meeting the live meeting will run appropriately for what appears to be a random amount of time then will drop the connection, re-open and connect back in and display as being a third user in the live meeting. Where their original log-in appears to still be there but no audio for this 'ghost' user according to the LM client.

 

 

We will soon be upgrading to 10.1 where I will get to utilize the template F5 has provided but it does not appear to address AV and Webconf. Am I missing something?

 

 

Thank you for any assistance in this!
