I have a ufw firewall with the following rules:

Status: active
Logging: on (low)
Default: deny (incoming), allow (outgoing), deny (routed)
New profiles: skip

To Action From

22/tcp LIMIT IN Anywhere

80 LIMIT IN Anywhere

443 LIMIT IN Anywhere

22/tcp (v6) LIMIT IN Anywhere (v6)

80 (v6) LIMIT IN Anywhere (v6)

443 (v6) LIMIT IN Anywhere (v6)

These rules set a limit to the number of requests on ports 22, 80 and 443. The rules are obeyed except when I use a vpn like ExpressVPN.

How can I set a limit to the number of requests in order to block a hacker that hides behind a vpn?
