AzurePack: Components for Website Feature failed to install

I had to install a new Frontend and Publishing server for my Web Sites components inside Azure Pack, unfortunately the installation failed so I had to find out what was wrong.

First check on the troubleshooting step by step list is to control the Firewall, which also revealed the problem:

The automatically created Firewall Rule for the “WebFarmAgentService” which is used to install the rest of the components, only enables the rule for “Public interfaces”. So my interface that’s being used, that’s connected to the Domain, did not obviously allow that traffic.

Enabling “Domain” in the Firewall Rule solved the problem, and the installation went through! I can’t see any reason for the devs to make that decision to only enable the rule for Public… But maybe there is some strange reason that you guys can come up with?
