Good afternoon.
How to prevent a client (or all clients) in Wireguard from connecting to any IPs other than local ones?

Local: 10.1.0.2 on the client, 10.1.0.1 on the server side.
It is necessary to prohibit any connections from clients, except for local ones (prohibition of access to the network).

Thank you.

Answer 1

The same as for any other network activity passing through the server - the firewall rules on it.
