Scriptcase 9.6.015 Port Forward from firewall

OPNsense Firewall (21.1.7_1-amd64)
Scriptcase (9.6.015)

[WAN 1.1.1.1] - (FIREWALL- [DMZ 2.2.2.0/24] - [ScriptCase LAMP 2.2.2.1]

I’ve configured a port forward on the WAN interface of the firewall for incoming connections
1.1.1.1:80 to be redirected to the Scriptcase LAMP at 2.2.2.1:80.

The firewall port forward does work (from the WAN going to 1.1.1.1/SCappGrid - redirects to
2.2.2.2/SCappGrid). The grid is displayed and I can search with in the grid.

If I try and edit a grid row, I receive an error message “INVALID DATA” - no other details on
the error.

Im assuming when I try and edit a grid row (on the port forward), ScriptCase is trying to access
the real LAMP server address (2.2.2.1) and throwing the error.

Is there some setting in the Scriptcase app to ensure a firewall port forward will work?
