Port Forwarding - Adding and removing itself

[DBE]

Hi,

We have tried to open a port in the router for SQL server access, however it is showing the following in the log:

15:13:36, 11 Feb.

:This Rule has been applied successfully: [id:152, InternalClient: 192.168.1.65, External Ports:(5000,5000), Internal Ports: (0,0), Protocol: TCP/UDP]

15:13:36, 11 Feb.

:Adding port mapping rule by User

15:13:36, 11 Feb.

:Updating port mapping rule (152) by User

15:13:36, 11 Feb.

:Deleting port mapping rule (152) by User

15:13:36, 11 Feb.

:Updating port mapping rule (152) by User

We have read some other threads that suggest turning uPNP off and trying again but we are having no luck.

Also, we have tried using the standard port 1433 but are having the same results in the logs.
