Skype for Business – Additional Edge port required?

Whilst waiting for the general release of Skype for Business server I’ve been having a little look through the TechNet documentation currently available.

I noticed this little gem at:

Now the Edge firewall rules still reference Lync 2013 and make no mention of 4443 on the external interface (only the internal replication port) so we’ll have to wait until it’s released to see if this is a new port or not.


A colleague has pointed out that the new workloads poster references 443 for outbound for Skype, so maybe it’s just a typo, will still have to wait to see.
