I have a distributed environment running with Windows Server 2012 R2, and the firewall enablement has never gotten in the way. During the TS installation, behind the scenes, Tableau takes care of opening the required ports. The only issue occurs if you have other apps running on the nodes and then there is the possibility of port conflicts.
What operating system are you trying to install with?
What kind of error are you seeing?
I got no error, I just read in admin guide and got confused with the stuff.
Even we have tableau server installed while keeping firewell enabled.
so what problem are you having? It's been 2 months since the original post.
As of now, no problem. I just want to be well informed with the best practice.
