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.
