Dear All,
Have you realized that DNS-327L NAS forwards the standard ports to itself on your UPnP enabled router? I mean 80 and 443 is routed to the NAS and 22 also if backup service is enabled (aka. ssh). I double checked in my router and it shows these ports are forwarded via UPnP.
I couldn't find any option to disable this "feature" (what is more like a bug and security hole for me) so I disabled the UPnP in my router. I have the latest 1.03b3 FW on my NAS.
BR,
denx
