NAT reflection work?

[slickdakine]

Hi,
Does NAT reflection work in 18.1?
I'm trying to setup basic NAT reflection for a game and it isn't working.
The port forward rule works, and everyone on the outside can see the game, but no one can see on the inside.
I forced port reflection on the port forward rule, and also enabled the following under settings/advanced:
Reflection for port forwards
Reflection for 1:1
Automatic outbound NAT for Reflection
I noticed there is no longer a choice for PUREnat and Nat-Proxy that used to exist. Seemed like the Nat-Proxy is the one that I had to use in the past. Now it only lists enable/disable.
Anyone know?
Thanks-

I am using multi wan and openvpn. Not sure if it still matters:

I couldn't get NAT reflection to work in 17.7 but it "just started to work" some time after the 18.1 upgrade.
My settings are very similar:

In the Port Forward rules:
NAT reflection: Use system default
Filter rule association: Pass

Firewall / NAT / Outbound:
Automatic outbound NAT rule generation

Firewall / Settings / Advanced:
Reflection for port forwards: Enabled
Automatic outbound NAT for Reflection: Enabled

I have only one IPv4 WAN interface and don't use OpenVPN.
