Author Topic: (critical security issue) DNS-327L "always open" if ports are forwarded  (Read 3411 times)

My biggest concern with this device:
  • I wanted to use my DNS-327L as from web-accessible storage, so I've registered a new dyndns account for this device. No matter if I enable or disable this service, I am always able to acces the device from external devices. I literally have no choice of stopping it until I disable port forwarding in my router. (there is no note that it may take several minutes for changes taking effect...)
  • Network speed is very poor. I've used a USB connected hard drive with my DIR-860L and had almost 100% of the available upload speeded for downloads from external. Today I got 1/10 with downloads from DNS-327L, again no matter if the services are enabled or disabled.

A minor concern:
Every 2 seconds the hard drives do a little seek or something. Is this caused by the Raid-1 configuration? Or by using Western Digital Red 3 TB (WDC WD30EFRX) devices?

edit: I will make a new topic for the periodic activity

  • Link>What Firmware version is currently loaded? Found on the routers web page under status.
  • What region are you located?

Internet Service Provider and Modem Configurations
  • What ISP Service do you have? Cable or DSL?
  • What ISP Modem Mfr. and model # do you have?
  • Is ISP Modem/Service using Dynamic or Static WAN IP addressing?
  • What ISP Modem service link speeds UP and Down do you have?
  • Check cable between Modem and Router, swap out to be sure. Link> Cat6 is recommended.

I recommend that you phone contact your regional D-Link support office and ask for help and information regarding this. We find that phone contact has better immediate results over using email.
Let us know how it goes please.
