NAT Reflection question

[akula169]

Is there a cutoff or upper limit on ports for NAT reflection?

I can access, 80 and 443 without an issue.  Other stuff like VPN that use the higher ports don't seem to work?

Also, does the reflection apply to uPnP configured ports?

Reflection does not apply to uPNP.

It works on any port so long as it's not a port range larger than 500 ports. So if you forwarded 15000-15400 that would work, but if you forward 15000-16000 that wouldn't reflect.
