A limitation of RADIUS version 1.0 (RFC 2138) limits authentication to 16 characters. In FW-1 the only difference between the two versions is the ability to pack long passwords inside the transmitted packets.
Use a RADIUS version 2.0 (RFC 2865) compatible RADIUS Server. Contact your RADIUS Software vendor to ensure version 2.0 compatibility. Configure the RADIUS server object in SmartDashboard to reflect the use of a RADIUS ver 2.0 compatible platform:
- Open SmartDashboard.
- Select 'Manage' > 'Servers'.
- Open the RADIUS server object properties.
- Select 'Radius ver. 2.0 compatible', under 'Version'.
- Click 'OK'.
- Install the Security Policy to all affected authentication gateways.
Embedded GAIA devices does not support RADIUS version 2.0 for Remote Access VPN authentication.
RFE will be required.
