Hello, I will try to explain briefly.
Have a Synology NAS, with local ip: 192.168.1.100, there are some different web servers, each one of them in a different port, 3000, 40500, etc. The NAS has inbluid reverse proxy, and my NAT rules are configured, so I can access all well.
The problem is, when I access from LAN, to my public IP (or domain mynas.com) to access any of those web servers, the incoming IP in all of them is shown as the gateway local IP, 192.168.1.1
I have read many articles about Hairpin NAT and view every video on youtube, but cant view where is the problem.
Somebody can point my to the very firt point I have to do to avoid that?
