How to block all incoming ip addresses using Windows Server except one in Windows Server 2008?
There is Windows Server 2008.
The purpose of the task is this.
Due to the importance of protection against hacking, network attacks, I need to block it so that it is offline for the whole world, only open to one IP address.
If it's not difficult for you, please write a ready-made example of how you can disable all incoming IP addresses including ports using Windows Server 2008 tools, and then allow only one IP address.

Answer 1

The built-in firewall in Win2012 and so by default (like most firewalls) blocks ALL incoming connections (including those from the local network), except for those specifically allowed.
To open a connection from a specific IP address, you need to create an inbound rule in Windows Firewall (Start - Administrative Tools - Windows Firewall - Inbound Rules - Create Rule - Custom - Next - Next - and specify the remote IP address from which connect.)
In addition to filtering by IP, filtering by the ports / programs used would not hurt (after all, you don’t need all the services remotely, right?).
In general, filtering is usually configured on the gateway / proxy in order to protect not just one server, but the entire local network.
