Rate limit connections to port by IP

Installing and Using OpenWrt

I have a port forward defined to forward SSH connections to my local server and would like to rate limit connections on this port at the router on a per-IP basis.

I found the "Limit matching" option under the "Advanced Settings" tab for this port forward, will enabling this setting accomplish the above? If not, how can I accomplish this?

It can accomplish that, but if you don't define the IPs it will be for all connections. I don't know if there is any module to use per IP connection limiting.
