Why QNAP Redirects custom external port to own 443?

[carlots251]

Hi

I have a IP domain, beside a simple router with firewall.
I Have several port on nat like:
http://My_ip:my_custom_port1 > http Qnap
http://My_ip:my_custom_port2 > VirtStat Qnap
My_ip:my_custom_port3 > RDP of a VM on VS Qnap
These works. ok.

I open
https://My_ip:my_custom_port4 > Https of a Webserver of VM >>> this redirect to qnap! What's the problem? I check the configuration of the nat several times and it' right:
External port > external IP > Internal Port > internal IP

Port forwarding must go to the virtual machine LAN IP, no to the NAS LAN IP.
