Access firewall from wan ip address

[hjint]

On version 18.1.13, I was able to access the firewall from the WAN side via the firewall's WAN IP address, but on version 18.7.1, I am not able to access the firewall from the WAN side via the WAN IP address.

I manage a network at a friend's home office also with OPNSense but still on version 18.1.13. This network setup is a copy of my setup. The only difference with my setup is that my setup is already upgraded to version 18.7.1.

I can still access the firewall on version 18.1.13 with port forwarding on the WAN port but I can not access the firewall with version 18.7.1 with port forwarding or from the router side. The logs don't show any deny messages on the WAN IP address of the firewall or the WAN IP address of the device which I try to access the 18.7.1 firewall. Only a blank browser page appear without the login screen. The System: Settings: Administration is HTTP on port 8080 and HTTP_REFERER enforcement is disable.

I think that I am missing a setting in 18.7.1, but I can't figure out what am I missing. Any ideas please?

So is your goal to allow HTTPS access to the WAN IP of the firewall for GUI management?

If so, you just need to make a rule that allows HTTPS traffic to the WAN IP and there wouldn't be any port forwarding needed as it's local to the firewall.

An example WAN Rule would be like my VPN rule.

Just change the port to HTTPS and protocol from UDP to TCP:
