Opened: Jun 06, 2018

Severity: 3-Major

Symptoms

When VPN tunnel is terminated, 'Radius Accounting-Request (STOP)' always includes AVP Framed-IP-Address=0.16.0.0 instead of the assigned IPv4 addr to the PPP tunnel.

Impact

APM sends 'Radius Accounting-Request (STOP)' that includes the AVP Framed-IP-Address=0.16.0.0 value instead of the assigned IPv4 client IP address.

Conditions

-- Network Access resource is configured with both IPv4 and IPv6. -- PPP IP address can be either static (obtained from RADIUS) or dynamic (obtained from the lease pool). -- Using an Edge client or a browser. -- VPN tunnel is terminated.

Workaround

Configure only IPv4 IP addresses for the Network Access resource.

Fix Information

Include Framed IP Address in RADIUS Acct STOP message only when it is a valid IPv4 address.
