Your question is similar to the other one that you opened in regarding to the mobility clients. the ports are the same there are no difference between the required ports for public connectivity.

For Lync Edge
sip.domain.com ports (443 and 5061 tcp only)
av.domain.com ports (443, 3478 tcp/udp, 50000-59999 tcp/udp)
webconf port (443 tcp)

For Front End
Meet.domain.com, dialin.domain.com, lyncdiscover.domain.com (mobility autodisocover), webservice.domain.com should all be configured on the same public IP on port 443 as they only connect using HTTPS when configured on Any reverse proxy like ARR for instance.

Dear Mohammed Hamada,

If you try to use Lync Peer to Peer and  monitor the ports using Resource Monitor tool in windows you will discover another ports specially when you try to share application or send picture, that's why i ask again and i hope if you can try it and then let me know, we all know the info mentioned in links, but when you practices the work you will discover more, waiting your feedback after you check...

If you're on the same network yes, if not Peer to peer connections are made through the server first and then the clients will talk to eachother directly so no server ports need to be configured... if you have a firewall on the client PC or an Internet security application that has strict firewall rules like Kaspersky then you might wanna consider configuring the required Lync ports for that.
