/ip firewall filter add chain=forward protocol=tcp tcp-flags=syn connection-limit=101,32 action=drop

This rule will allow 100 TCP simultaneous connection per network user.

1) Upgrade your router to the latest MikroTik RouterOS version.

2) your rule allows 3 connections per network.
4 - is allowed connections, 24 - subnet mask.
Change connection-limit configuration.

It should work, however it's recommended to ugprade.
Note, given rule will limit TCP connections.
