UPnP not working

i don't use it anyway, not a problem for me

UPDATE: Someone on Reddit recently said that, "miniupnpd decided they wouldn't allow mapping to RFC1918 addresses any more." In my case, this is true; my pfSense is connected to the ISP's modem and set up in the DMZ. That might be the problem, since the modem gives it a private IP. And that might explain why UPnP worked with @johnpoz since he obviously has his pfSense directly connected to the internet, indicated by the black dash on his IP.

ok so after finding why my upnp made my system crash, i was able to test this on a virtual machine in a double nat situation,
it does not work

upnpc -a 192.168.123.2 1234 5678 tcp
GetExternalIPAddress failed
Addportmapping failed with code 501 (Action Failed)

if i set "Override WAN address" and put a non rfc1918 it work.
if i try this without double nat, it work

this was pfsense 2.4.5

I have never come across this error in my testing, which sucks since it could have saved me time. Anyway, how can we enable the "ext_perform_stun=yes" to fix the issue (hopefully)?

Override WAN address

i tested it also, but found random stuff on google,
you can use Override WAN address
or
you need to modify /var/etc/miniupnpd.conf and add
ext_perform_stun=yes
ext_stun_host=stun.onesuite.com
and manually launch miniupnpd -d -f /var/etc/miniupnpd.conf

please take in mind that i don't know what/who onesuite.com is, it report your wan ip address.
anothe public stun server is stun.stunprotocol.org
STUN=
Session Traversal Utilities for NAT (STUN) is a protocol that serves
as a tool for other protocols in dealing with Network Address
Translator (NAT) traversal. It can be used by an endpoint to
determine the IP address and port allocated to it by a NAT

maybe we can add this options to miniupnp webgui if it's missing and it's needed, idk

You can create feature request on the redmine.pfsense.org for this.
it's easy to add to WebGUI, and it may be useful for some ISPs issues.

but https://redmine.pfsense.org/issues/10398 needs to be resolved first
