• Hi

    I have the following situation:

    I configured the pfsense as a transparant bridge.
    My setup:
    pc –------------------------------ pf ------------------- switch
    192.168.2.x---- - pf - --- switch

    I just want to create a firewall within the same network( later i want to use this with external ip's)

    Now i was testing my firewall rules and came to some strange conclusions.

    I have blocked all traffic on lan and wan (all ports, udp and tcp).
    When i do a portscan from a pc connected to the switch to the pc behind pf, I notice port 25 and 110 are closed

  • does the PC have a firewall on if so it is likely blocked those ports unless you otherwise specify for it to be open….

  • The firewall of the pc is disabled.
    The problem is that pfsense doesn't block those ports. :s

  • What rules do you have in your firewall for LAN and WAN, take a screen shot and post it if you can.

  • Here are my rules

    first is Lan, second is wan

  • @daniel:

    I have blocked all traffic on lan and wan (all ports, udp and tcp).

    Your screenshots do not prove that.

  • After some investigation I came to the conclusion my Wan an Lan were switched.
    That was the reason the ports were open.

    Thx for the response.
    this can be closed.
