# sk180723 - RADIUS authentication sent with wrong IP address for SmartConsole on Multi-Domain Security Management Server

| Property | Value |
|----------|-------|
| Solution ID | sk180723 |
| Date Created | 2023-03-14 |
| Last Modified | 2025-06-23 |
| Technical Level | General |
| Products | Multi-Domain Security Management Server |
| Versions | R81 (EOS), R81.10 (EOS), R81.20 |
| OS | Gaia |

## 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.

## Solution

This problem was fixed. The fix is included in:

* [Jumbo Hotfix Accumulator for R82](https://sc1.checkpoint.com/documents/Jumbo_HFA/R82/Default.htm) starting from Take 25
* [Jumbo Hotfix Accumulator for R81.20](https://sc1.checkpoint.com/documents/Jumbo_HFA/R81.20/Default.htm) starting from Take 99
* [Jumbo Hotfix Accumulator for R81.10](https://sc1.checkpoint.com/documents/Jumbo_HFA/R81.10/Default.htm) starting from Take 177
