Trying to set up a Buffalo NAS drive web access through my Vigor 2850. The Buffalo reports an error, "
UPnP Gateway not found and/or doesn't support port forwarding, use manual setup."
I've gone into the Vigor 2850 settings, Applications/UPnP and enabled the service and their control and status services. - no change.
I don't know what else to look at or what to do next. Any help would be most welcome.

have not used any buffalo products but i think if you google the message may be more helpful
I have just done a quick search "UPnP Gateway not found and/or doesn't support port forwarding" and gave me few answers
here one but not sure if is for your case but maybe with manual port forward or port mapping?
