I must manage a school network of about 60 Windows computers that are setup as workgroup computers and not in a domain. To ease configuration I am going to enable PowerShell remoting on all computers. (I know about Enable-PSRemoting and how to set this up in general) To limit security risks as far as possible, remoting to these computers should only be possible from my administration PC with a certain IP address.
So consider this example:
Computer 1: only accepts remoting connection from admin, not from computer 2 Computer 2: only accepts remoting connection from admin, not from computer 1 Admin computer: can remote on all computers
I'm not sure how to set up the Windows firewall on the computers to allow traffic of the WinRM protocol only from one IP address. The whole network is set to 'private'.
Can somebody help me out with enabling the correct firewall rules?
