When adding a RADIUS service to the Secret Double Octopus platform for the first time, you must allow the RADIUS port and protocol through the Linux firewall of the Authentication Servers. This is not done by default when you create the service.

This document describes:

  • How to verify whether the required RADIUS ports are currently allowed through the firewall
  • How to configure the system to allow the ports through the firewall

This document is meant to serve as a baseline guide for general Linux system administration. Actual commands may vary according to the exact version and OS of the Authentication Servers on which you are running the Secret Double Octopus platform.
