Tech Note – RADIUS Troubleshooting 

Overview 

RADIUS Authentication, Authorisation and Accounting (AAA) is a core component of the 
amigopod platform and therefore being able to effectively troubleshoot any authentication 
issues between Access Controllers (RADIUS NAS devices) and the amigopod is essential. 

By default amigopod is configured to communicate RADIUS traffic on the following ports: 

o

 

Authentication transaction on UDP port 1812 

o

 

Accounting transactions on UDP port 1813 

o

 

RFC 3576 transactions on UDP port 3799 

The inbuilt firewall rules that protect the amigopod kernel are automatically provisioned to 
allow traffic to flow to and from these ports. 

Basic Configuration 

When configuring your network environment you must ensure that your Access Controller’s 
RADIUS server definitions for both Authentication and Accounting are configured to match 
the above port settings. If your deployment demands that this default ports be changed from 
1812 and 1813 these can be modified through the amigopod web interface under RADIUS 
Services
