I'm having a problem with port openings (including NAT)


  • Hello,

    As a new pfSense user I'm wondering what did I done wrong regarding the port openings because none of the ports I want to open seem to be opened. My settings can be seen here:

    (The ports are not blocked by my ISP because they were opened while I was using my previous router (ASUS RT-AC3200). Asus is now working only as an AP with no NAT or firewall features on. Rebooting pfSense didn't seem to have any effect on this.)

    pfSense version: 2.3.2-RELEASE-p1 (amd64), built on Tue Sep 27 12:13:07 CDT 2016


  • On the WAN rule under advanced..  Click the "Log" box and watch your firewall logs for traffic bound for the port.  The source IP will show up with a green check mark in the log.

    The more correct way to diagnose would be to do a packet capture and see if you see any traffic headed in the WAN port.

    Your setup looks correct to me.


  • Thanks for the information! It seems that at least some of the ports are opened. :) Obviosly some of the ports opened right after client's restart so it might have been up to that. Let's see how will this work in the future.
