Port Requirements for Lync 2010 Application sharing with external user

For Small buisness network this topic may not be that much usefull,but for a Large enterprise with restricted network setup this will be very usefull.Below requirements i captured using lot of testing and network tracing.When i recieved this requirement there was no articles clearly mentioned about how we can achieve this,all was mentioned some specific ports for application wise.

Scenario:Users are sitting in a restricted network.User only have text IM access with othere users as well as federation/external users.Requirement here is to application sharing with external/federated users.After the study i concluded with below ports for application sharing with external users.

Public to edgeserver:

TCP/443

UDP/3478

TCP/8057

TCP/50,000-59,999 (Outbound only)
From the internal Client to the internal Edge:

TCP - 443
UDP – 3478
Above ports for only to conference and Media traffic from internal user to External user.
If you wanted to have internal conference between 2 restricted netwok users below is the port requirements.
