I have a Linkstation Live for which I set-up tehWebAccess a week ago and it worked first time perfectly. I subsequently purchased a Linkstation Pro and also set-it up on my network. I then attempted to change the "BuffaloNAS.com Name" for my Linkstation-Live, but get the message "UPnP Gateway not found and/or doesn't support port forwarding, use manual setup." I also tried to enable the WebAccess for my new Linkstation-Pro, but receive the same message. I have not changed anything on my network or Router. My linkstation-Live Webaccess still works fine (but I can not change the name or enable WebAccess for my Linkstation-Pro). What can be the reason for this and how do I fix it?
