Idea for working with NAT

[eugenesmsk]

Hi, on my example: I have a server with 3x-ui behind NAT. So inside my local network I can only use the local IP address to connect and cannot use my public IP address. Outside I can only connect via public IP address to my server (ports forwarded to the server with 3x-ui). So I have to have 2 identical configurations but with different IP addresses. Is there any possibility to add in profile settings the possibility to specify an IP address behind NAT (internal address)? In addition to that, this would require an automatic check of the real IP address when connecting or in case of connection loss. If it coincides with the public IP address specified in the settings, then the connection should be through the internal address. And if it doesn't match, it should be through the public one.
