AutoBlock open Port



  • I have a pFsense firewall with firmware 2.3.4_1 where i encounter an issue on a daily where port 5555 NAT stops working after 12 to 48 hours. Only a reboot of the firewall solves the issue.

    Anyone have any ideas, cause i'm out :-)

    PS: Also the WAN interfaces is bombarded with blocked actions from a port scan…
    (Random IP's and ports)

    This is common. As long as you have the rules, you are good

    What service is running on 5555?



  • It's a custom CRM application



  • Sounds like it has something to do with the states (The way your CRM reacts to states). Under rules for NAT did you make any changes in "Advanced Options" section for States? What is the "State Type" and "State Timeout" settings



  • State Type = Keep
    State Timeout = *Empty
