AutoBlock open Port

[adminvsvvsv.be]

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 :-)

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
