Ports showing open



  • pfsense 1.2 Live RC1

    This may have been added to help elude attackers?

    I have noticed when doing a port scan alot of ports are open. I know in earlier versions the WAN port was firewalled unless you specifically enable a port.

  • Have you enabled the firewall ? Does it not bypass ?



  • What tool are you scanning with?  What firewall rules have you enabled on the WAN?  And, as Matts said, did you disable the firewall?



  • Either you aren't scanning pfsense, or you opened a whole host including all ports to the world. That's the only way you could possibly see that large of a number of open ports. That looks like a typical Windows Server box with some odd stuff thrown in.



  • I am using nmap

    By default the WAN interface is firewalled, I did not diasable it.

    Perhaps I am not connected to the right box as dyndns may not be working.
