On a brand new install of Windows 2008 core (for use as a hyper V host( There are 4 ports open to the world:
135/tcp open msrpc 445/tcp open microsoft-ds 2179/tcp open unknown 49154/tcp open unknown
I tried blocking one of them with the rule
netsh firewall delete portopening protocol=TCP port=135
nmap -PN still shows it as open! I am a lot more experienced with Linux, so I am not sure if these ports are a security risk or not, but I would rather close them to the world.
How can these ports be blocked using
netsh advfirewall firewall ?
To expand on this further, what are the most locked-down firewall rules that can be put in place to allow remote management using server manager, and hyper V manager, from a single trusted IP address. To put it another way, I want to manage these new servers from a single remote machine, and allow no access to anyone who is not using that IP.
