Hi everyone,
I have a dual WAN setup that I want to get UPnP or at least an open NAT working on.
Due to the use of 2 different PC's and no support in OPNSense for port triggering I believe UPnP is my only option?
I have set this up following various guides but they are invariably for single WAN understandably.
It is set up as following:
Allow UPnP Port Mapping
External interface - WAN
Interfaces - LAN
Default Deny
Entry 1 - allow 1024-65535 xx.xx.xx.xx/32 1024-65535
NAT outbound firewall rule xx.xx.xx.xx/32 source, any destination, static port
Where xx is the IP of gaming PC 1 (Gaming PC 2 is yet to arrive but would be added below this in the same way.)
Nothing ever shows up in UPnP rules, NAT in games is always strict so it appears to not be functioning at all - where have I gone wrong?
For testing purposes my firewall rules have been changed from OPT1-WAN failover with gaming traffic specific rules of the opposite (something else that doesn't work!) to WAN-OPT1 failover to ensure only one connection is used.
Also tried everything in the thread below now:

Still no luck with getting anything to trigger UPnP :/
