      Hello,

      We have several pfSense firewalls (virtual and appliance) but for one system I am having trouble with blocked traffic through the firewall.

      Internet –> WAN Interface --> LAN Interface -- switch on LAN --- Computers

      We have a service on port 10000 that we need to access.

      We get the following Firewall log entry
      @5(1000000103) block drop in log inet all label "Default deny rule IPv4" for the traffic

      The log entry is
      X May 2 10:50:59 WAN 203.48.200.1:16041 14.201.1.2:10000 TCP:S

      14.200.1.2 = IP Address on WAN interface (PPPoE)

      1. Port Forwarding rule:

      WAN TCP * * WAN address 10000 192.168.1.200 10000 Monitoring system

      2. WAN Rule, automatically generated after Port Forward set up.
      This is after the auto-generated Deny rules for RFC 1918 Networks and Reserved Addresses

      Pass IPv4 TCP * * 192.168.1.200 10000 * none   Monitoring system

      3. NAT - Outbound

      Auto created rule
      WAN 127.0.0.0/8 192.168.1.0/24 * * * WAN address * Auto created rule

      no other rules

      I really cannot see what the problem is as we have similar rules on other firewalls fo other services (HTTP/HTTPS/SMTP)

      Any help appreciated

        A reboot of pfSense resolved this.

        Of course, why should we have to reboot pfSense to get this to work?

          You wouldn't have to reboot, but you would have to reload the rules.. If your rules did not load, then sure a reboot would load them.

          Was there any error in the loads that your rules didn't load correctly?
