Correct way to enable external web access for administration?

[Guest]

I have tried to enable remote web administration for Endian 2.3 by creating firewall policy and failed.

Then I found that Endian has System access configuration option under Firewall tab.

Since we have several public IPs, so I try to use only one of the IP address on the RED interface, but also failed.

I found that i have to select RED or Uplink main (Main uplink) - IP: All known

If i use any specific public IP 173.nnn.nnn.210 - 173.nnn.nnn.214, then I was unable to access the firewall admin interface.  Why?

And did I configure it correctly?   Please see linked pic.
