Limit number of connections from one IP to checkpoint

[minhhaivietnam]

Hello Checkmate,

I have a Checkpoint R80.10 facing to internet. I saw a lot of connections to my webserver behind CP in smart console log like this:

My question is how I can rate the number of connections of above IP , for example: when it already has 20 connections , a connection of 21th coming will be droped?

Thank a lot !!
