UPnP still broken on R6400

UPnP stopped working on the R6400 as of a recent firmware upgrade; I'm thinking it was 1.0.1.42 in June.

 

1.0.1.44 is now out, and UPnP still doesn't work.

 

Am I correct in assuming that this is a known problem? And that it will be fixed some day?

UPnP is fixed by R6400 firmware version 1.0.1.46.

 

I presume this doesn't  open exposure to WAN-side UPnP attacks.

Re: UPnP still broken on R6400

I have the same issue.  UPnP does not work after the firmware upgrade.  I had to use port forwarding to access my IP cameras.  Also, the camera dns names no longer work. I have to now use the actual IP address of the router to access the cameras.

Re: UPnP still broken on R6400

My firmware version is V1.0.1.42_1.0.28.  I noticed there is a fix for the R6700.  Any chance getting an update forR6400?

   What are these "the camera dns names"?  Are you saying that some DDNS
feature is not working, or what?

   Does reverting to an older firmware version help?

Re: UPnP still broken on R6400

I could not find the previous versions of the firmware.  Do you have a link?

 

Amcrest is the DNS server.  This no longer works with the latest firmware update.

   Visit http://netgear.com/support , put in your model number, and look
for Downloads.  For older versions, under Firmware and Software
Downloads, look for "View Previous Versions".  Find the kit(s).
Download the kit(s) you want.  Read the "Release Notes" file for
instructions.

   That tells me nothing about anything.  What, exactly, "no longer
works"?  As usual, showing actual actions with their actual results
(error messages, LED indicators, ...) can be more helpful than vague
descriptions or interpretations.

Re: UPnP still broken on R6400

I found the older versions of the firmware.  I read in previous posts that stepping back to a previous version works.  I have the port forwarding working so that will not be an urgent task.

 

DNS is domain name search.  So instead of typing in something like www.google.com, you would instead type in the IP address, like 201.34.28.91 (not actually googles IP).  So when I type in the DNS name for my camera, it goes to Amcrest to get the IP address.  I am guessing because UPnP is not working, it is not sending that information to Amcrest.  Instead I have to write out my IP address of my router to get to the cameras.  When I say it does not work, that means when I type the URL, it does not find anything.  If I type the actual IP numbered address, I can get to the cameras.

Re: UPnP still broken on R6400

I reverted to R6400-V1.0.1.34_1.0.24.chk and now the UPnP and the DNS names works correctly.  Looks like there is a bug in latest firmware or there is an incompatibility with Amcrest cameras.

   "DNS" is Domain Name System, and thanks, but I have some grasp on it.

   When you specify "the DNS name for my camera", the computer/device
involved "goes to" whichever DNS server it always uses, which depends
on the network (DNS) configuration of that computer/device.  What it
finds there may depend on any number of other DNS servers on the
Internet.  It's not obvious that the DNS server used by that
computer/device has anything to do (directly) with your camera vendor,
unless that vendor operates some DDNS service.

      https://en.wikipedia.org/wiki/Dynamic_DNS

   Without some clue as to the actual DNS name which you're using, it's
tough to guess what might be failing when you do whatever you're doing.

   And perhaps UPnP is required for some DDNS service to work properly,
but there's not enough information here to say.

Re: UPnP still broken on R6400

Amcrest does have it's own DNS server.   Rolling back the firmware corrected all of the issues.  Looks like a Netgear firmware bug as reported by several other users.  Sorry you were so annoyed with my attempts to answer your questions.

@NMCEngineer

 

I had a quick question.  Can't you just use a DynDNS hostname with a port to see your feeds?

 

yourhostname:[port] 

 

I put 1.0.44 on my R6400 2 weeks ago, however, I haven't tested UPnP.

 

Thanks

Re: UPnP still broken on R6400

That option quit working once I upgrade the firmware.  Once I rolled it back, it worked again.

Message 12 of 16

Re: UPnP still broken on R6400

That option does not depend on UPnP.  You forward the port and point it to IP of the camera or feed.

Re: UPnP still broken on R6400

If you don't have port forwarding enabled and use UPnP instead, the latest firmware caused the UPnP not to work.
