Netgear WPN824v2 Port Forwarding Issues

I came across an error when setting up SSH port forwarding on a WPN824v2 router

Port conflict with other service.

I found the way to fix this was to turn off UPnP. After that I could add the port forward.
I also found that Logmein suddenly became much quicker. So it could be that UPnP is not very good on this router.
