# RADIUS authentication sent with wrong IP address for SmartConsole on Multi-Domain Security Management Server

**Product**: Multi-Domain Security Management  
**Version**: R80.40 (EOS), R81 (EOS), R81.10 (EOS), R81.20  
**OS**: Gaia  
**Last Modified**: 2025-06-23

## Symptoms
- Traffic shows that the RADIUS requests leave the Multi-Domain Server with the IP address of the Multi-Domain Server regardless of which interface is used.
- Issue occurs after upgrade of Jumbo Hotfix.

## Cause
If there is a Security Gateway between the Multi-Domain Server and the RADIUS server, then the Security Gateway drops the traffic from the Multi-Domain Server because of anti-spoofing, which causes RADIUS authentication to fail.

This problem was fixed. The fix is included in:
