Blocked packets on WAN interface

  • 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 TCP:S = IP Address on WAN interface (PPPoE)

    1. Port Forwarding rule:

    WAN TCP * * WAN address 10000 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 * * 10000 * none   Monitoring system

    3. NAT - Outbound

    Auto created rule
    WAN * * * 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?
