PEPWAVE AP One 300M PROBLEM WITH PEPVPN TO BALANCE 380

Background:

  • An AP One 300M - 3.5.5 BUILD 1900 deployed in router mode - fixed IP address.
  • A Peplink Balance - 380 8.0.0 8.2.1 build 5134 - fixed IP address. Serves as a PepVPN hub to a number of spoke devices.

Test case: dont is possible establish a PepVPN connection between the two.
Issues

  1. Adding the AP One 300M to IC2 as a PepVPN device is a manual process. Easily achieved.
  2. The local ID generated (and set) in the Balance 380 hub is non-changeable and too long for entry into the web admin of the AP 300M.
  3. Using the Balance 380 serial number as an alternative on the AP 300M but the connection on the AP300 dont start.

Is the AP 300M simply too old for this, or are there ways to get them to establish the PepVPN?
We have a bunch of AP 300M devices lying about for italian civil defense
All help (or clarification) would be appreciated.
