Strange Message

[gallosp]

Hi, everybody
In my Pfsense system, the next message begins to appear in the system logs:

Jul 18 13:06:08 kernel: Limiting open port RST response from 617 to 500 packets/sec
Jul 18 13:06:07 kernel: Limiting open port RST response from 610 to 500 packets/sec
Jul 18 13:06:06 kernel: Limiting open port RST response from 607 to 500 packets/sec
Jul 18 13:06:05 kernel: Limiting open port RST response from 521 to 500 packets/sec
Jul 18 13:06:04 kernel: Limiting open port RST response from 567 to 500 packets/sec
Jul 18 13:06:03 kernel: Limiting open port RST response from 571 to 500 packets/sec

I have investigated in Internet and in the forum, Some people say that can be a DoS attack or a portscan or an no normal activity. But I haven´t found the solution for Pfsense. What can I do?

Thanks for everybody…

Most likely you're being port scanned and you have your firewall rules are much more open than they are by default and should be.
