Public IP Requirements for A/V Edge
So a few people get nervous when you tell them your going to need a publicly routable IP when implementing the OCS A/V Edge role for external A/V Conferencing. Then you tell them they'll need to open up 10,000 high ports, and you can see the blood drain from their faces. :)
Well it's not all bad news. If you understand how the protocols work the risk really isn't that high.
Chad Lacy has a great post discussing the security that is wrapped around the A/V Edge role, check them out here...
