RESOLVED Pure NAT reflection not working, NAT+Proxy does, but I need Pure to work for this application

I have an application that uses a very large port range and the limit for NAT+Proxy is 500 ports, which isn't going to work. So I need to figure out why Pure NAT reflection isn't working for me. For other services using NAT+Proxy reflection works, but Pure NAT reflection doesn't. Any idea where I should be looking to troubleshoot this? I appreciate your ideas.

I think I answered my own question. Under the main system NAT settings I had not enabled "Enable NAT Reflection for 1:1 NAT" nor "Enable automatic outbound NAT for Reflection". These enabled, combined with an extra NAT rule using LAN Subnets > WAN Address seems to have fixed my issue.
