Port Triggering on Zywall USG 50

I have a Zywall USG 50, and I need to port trigger 443 so multiple machines can use that port.

I have set up a Firewall Rule:

From: WAN
To: Any (Excluding Zywall)
Schedule: None
User: Any
Source: Any
Destination: Any
Service: HTTPS
Access: Allow

Then I go to Routing and set up a route with port triggering:

User: Any
Schedule: None
Incoming: WAN1
Source: Any
Destination: Any
Service: HTTPS
Next Hop: Auto
Source Address Translation: LAN1subnet

I can't do a regular NAT, because that wants a specific IP (Port Forwarding)

When I go to our external address at 443, I get the Firewall login!  That should not be happening.

Any ideas?

The vendor mis-specified that he needed port triggering.  His application does not call out, so port triggering will not work.  He needed a port forwarded.
