Pfsense blocking portforwarded traffic on OPT interface



  • Hi all,

    Yesterday I made a new DMZ interface on Pfsense 2.2.5. Added a Default allow any rule for testing, portforwarded the needed port. But it is still being blocked by Pfsense. I can access the internet just fine from the server where the ports should be redirected to.

    I tested the portforward via canyouseeme.org . This method works just fine for checking portforwards on lan.

    Port forwards to the LAN interface work just fine. Tried to create a new one, and it worked immediately.

    Why does my portforward not work?

    In Firewall Rules WAN you need:  IPv4* * * 192.168.3.10 9987 * none

    Thanks for your reply. That rule was automatically created by creating a NAT rule. I added a screenshot with the rule now :) .



  • What do you need (ports, protocol)? UDP ? TCP ?

    I only need port 9987, UDP for Teamspeak



  • The blocks show TCP…? Testing: start off broad (IPv4*), then narrow down (UDP and/or TCP, port(s)).

    Feeling very stupid now. Checked my rules and saw an old rule matching my old teamspeak server on LAN… Removed and it works now. Sorry!
