Port Forwarding is not working



  • I am trying to setup port forwarding to access a web server on the LAN side of the pfSense server. I have it setup to forward port 444 on the wan side to port 80 on the lan side.

    WAN(444) > Server_IP(80)

    I have followed the instructions in the documentation for setup and troubleshooting.

    • I have logging turned on on the firewall rule and the logs show that it is allowing the connection to go through.

    • I can see the packets on both the WAN and LAN side using tcpdump.

    • I pinged the web server from pfSense to make sure it is still running.

    • I have also run a port scan on the web server using nmap on pfSense to make sure the server was listening on port 80.

    • I can connect to the web server while on the LAN side of the network.

    • The web server's default gateway is set correctly.

    I had to remove some of the IP addresses from the results below since they are publicly accessible.

    tcpdump results on WAN side:

    13:19:22.383616 IP <my ip="">.64393 > <wan ip="">.444: tcp 0

    nmap port scan:

    Starting Nmap 4.76 ( http://nmap.org ) at 2010-07-19 13:26 PDT
    Interesting ports on 192.168.5.10:

    Thanks in advance for any help.



  • Are you sure there isn't some kind of firewall/acl on the webserver blocking non-LAN hosts?



  • Double check the window firewall.  Try turnning off the window firewall to make sure.

    Then, Reboot the firewall state.
