NAT issues port fowarding



  • I recently dove into pfsense and after installing 2.0.3 and realizing that it did not support my nic drivers I moved over to 2.1.

    Everything has been perfect up until I'm having issues with port forwarding. I can not get anything to forward to my internal network. Below is my current setup.

    MODEM (DHCP) –--> WAN NIC (PFSENSE) -----> LAN NIC (PFSENSE) -----> SWITCH -----> PCs

    I can connect straight to it if I get rid of PFSENSE from the same box.

    Here are some packet snaps that I have done as well.

    On the LAN interface. (it's timing out connecting to my ip)
    00:41:45.249897 IP 192.168.1.100.49293 > XXXXXXXXXX.25565: tcp 0
    00:41:48.249879 IP 192.168.1.100.49293 > XXXXXXXXXX.25565: tcp 0

    Connecting in with the above rules on the WAN interface shows nothing.

    Port Test Results:
    Connection to 192.168.1.103 25565 port [tcp/*] succeeded!



  • You're trying to access your server from within your own LAN, judging by the 192.168.1.100 connection to your server @ 192.168.1.103.

    In the GUI, go to System/Advanced/Firewall-NAT/

    and enable NAT Reflection mode for port forwards.

    It is often necessary to reset firewall states after "major" rule changes. See Diagnostics -> States, click on Reset States tab, read and click on Reset button.
