NAT Problem!

  • Dear all,
    I have problem:

    • Client( cannot call to IP WAN + port 80 of Client( but Client( can ping to Client(

    How do I do for resolve problem  :'(?


  • Check your firewall rules first for WAN port on Pfsense.
    Second, on the Interfaces ==>> WAN settings page
    "Block private networks and loopback addresses"
    "Block bogon networks"

  • Hi kobzar,

    • From outside can connect to port 80 of client ( ) => Rule on WAN interface is correct.
    • On Wan Setting page, I unselected two option "Block private networks and loopback addresses" and "Block bogon networks", but I have recived the same problem.

    your drawing shows a duplicate IP client 2 is and then your trying to port forward that same address port 80 to something behind it.. that you hide???  WTF for?

  • Hi johnpoz,
    Client forward port 80 over Public IP of WAN Pfsense and then Client call to WANIP port 80 but not success!

    what???  Makes ZERO sense..  Clients don't forward ports…

    You have clients inside your transit network to the internet.. According to your drawing the wan IP of pfsense in this 10.0.0/? transit is, and then you also have a client with that same address..

    Post up your port forwards from pfsense.. And what is the IP of your device trying to access your forward..  Where is pfsense forward port 80 too??  What IP??  Something behind it??

  • Hi,
    I tried explaint the topology on attach file.

    That drawing is horrific!!!

    So your clients are behind pfsense on a 10.0.0/24 network??

    So pfsense wan is 125.x.x.x.. So you have a client trying to hit your webserver via your public IP..  For that to work you have to have setup NAT reflection.  But if your client on wants to talk to client why you not just resolve to on pfsense via a host override!!
