ASUS AC68U

I would like to block at the firewall level a number of IP that are trying to attack port 22 on a regular basis. Please could someone help me, I don't see anywhere in the router GUI to allow me to do this.

In the manual on page 69:
NOTE: When port forwarding is enabled, the ASUS router blocks
unsolicited inbound traffic from the Internet and only allows replies
from outbound requests from the LAN. The network client does not
have access to the Internet directly, and vice versa.

So you enable port forwarding and don't specify a rule (yet). This should block all unwanted inbound traffic. You don't have to specify the IP addresses that are trying to connect to your port 22.
