Configuring SQL instance firewall rules via PowerShell

Doing distributed environments setups rather frequently these days I realized that I really don’t want wasting my time setting up SQL Server firewall rules via GUI (I described the process here) and luckily enough Ryan Mangan already created such script. All I had to do is try it (confirm that it works), save it on GitHub and share on my blog for the benefit of wider community:

Set-ExecutionPolicy -ExecutionPolicy RemoteSigned 
#Enabling SQL Server Ports
New-NetFirewallRule -DisplayName “SQL Server” -Direction Inbound –Protocol TCP –LocalPort 1433 -Action allow
New-NetFirewallRule -DisplayName “SQL Admin Connection” -Direction Inbound –Protocol TCP –LocalPort 1434 -Action allow
New-NetFirewallRule -DisplayName “SQL Database Management” -Direction Inbound –Protocol UDP –LocalPort 1434 -Action allow
New-NetFirewallRule -DisplayName “SQL Service Broker” -Direction Inbound –Protocol TCP –LocalPort 4022 -Action allow
New-NetFirewallRule -DisplayName “SQL Debugger/RPC” -Direction Inbound –Protocol TCP –LocalPort 135 -Action allow
#Enabling SQL Analysis Ports
