What port uses Visual Studio to connect to TFS server?

Question

I'm using TFS Server 2013 en Visual Studio 2013. I want to make the TFS Server available via the internet so that (only) certain developers/ipaddresses can work at home.

My question is: What port does TFS Server use to connect to Visual studio? In other words: What port must I open/forward in my firewall for this to work?

Solution

There is no communication from TFS to Visual Studio as all traffic flows the other way.

Visual Studio connects with 8080 by default and 443 if secured.

I would however recommend that you leave everything to Visual studio online (http://tfs.visualstudio.com) as It is already secured and does not need any firewalls to be opened.
