Thank you. Then, I must remove "SSH" from services section
Yes.
and open port 22?
No. That's already done with the rich rule.

"ssh" here conflicts with your rich rule below. Here "ssh" is _always_ accepted. The rich rule will limit as intended, but that's not useful if you have "ssh" in service as well, because it always accepts (i.e. no limit).

Any rich rules that improve protection?
