(Flint 3) NAT loopback not working

Hi,

This is a known issue: the Qualcomm NSS hardware acceleration breaks the NAT loopback.
There are currently two solutions for this.

Solution 1:
Just disable the hardware acceleration.
The steps are as follows:

  1. Access the admin panel.
  2. Browse to Network > Network Acceleration > Disable.

Please note that this solution may reduce the rate between LAN and WAN.

Solution 2:
Add a DNS record for use by intranet devices while keeping hardware acceleration enabled.
The steps are as follows:

  1. Access the admin panel.
  2. Browse to Network > DNS > Click Edit Hosts button in the upper right.
  3. Create a new line, enter your intranet server's private IP address, leave a space, then enter your domain.
  4. Apply the changes and clear the DNS cache on your other devices to make it work.

Note that this solution requires

  1. The external and internal ports for port forwarding to be configured the same, otherwise you will need to use different ports when accessing from a public or intranet network.
  2. The intranet devices should use the DNS of BE9300, could not use the Encrypted DNS.
