## Symptoms

- * The Security Management Server has only one interface with an internal IP, and static NAT to a public IP is configured on the object.
* The Security Gateway that connects to the Security Management Server through the internal IP fails to send logs.
* Running `netstat -nap` on the Security Gateway shows that it is trying to communicate with the public IP, which is not reachable by this Gateway.

## Solution

This problem was fixed. The fix is included starting from:

* [Check Point R80.30 kernel 3.10](https://support.checkpoint.com/results/sk/sk152652)
