I have a domainname setup to access the NAS on my network. For example mydomain.comWhen I go to this domain on an external network, so out of home or on my phone provider, everything works fine.When I do this when connected to the main router of the RBK852 set, again everything works fine.When I am connected to the satellite however, it doesn't. Seems like a NAT loopback issue?

Yep, it's a bug. Apparently, only select devices in Netgear's line up were chosen to receive standard functionality that meets RFCs. Please ignore gb777 posts. They either don't know what they're talking about, or in the few cases where they do, choose to ignore it (the NAT loopback issue in particular was discussed here multiple times.)

An 800 Euro Mesh system that doesn't have the basic functionality of a 75 euro router... :(If only that was the only shortcoming of this overpriced system.

This sounds more or less to the issue I have. I set up port forwarding to one of my pc's and set up DDNS. When I access from within the same network the DDNS address it works. However the RBK852 is to a GS116eV2. Every device that is connected to the GS116eV2 can't reach the DDNS address. Additional info when I directly connect a GS105 switch and connect a pc to that one, then it works. So it would look that there's something wrong or missing with the GS116eV2 but after reading this thread I'm not sure if the cause is the switch of the RBK852. Thanks for any advice, hint, tip.

I have given up. If I connect the satellite with a cable, I get this issue. With this issue the whole set is useless to me. Without the cable connection the mesh is mediocre at best.Most overpriced useless router ever.

Something to contact NG support about and get additional help and information on.

  Found out the issue only exists when the satellite is connected with a cable for backhaul . When it is connected wirelessly it works as expected.
  
  Support won't do any good. I thought bugs were meant to be reported here?

    No, contact and report the bug there with support.
    
    When the RBS is wire connected, is it directly connected to the RBR or is there switch in between?

    Would be great to know if this happens with out the switch in line as well. Trying to gather some info.
    What is the model# of the ethernet switch in the configuration?
    
    If loopback is working with the RBR and not the RBS, lets try to figure out the RBS issue. Maybe if we can gather some info, we can work with NG on this. :smileywink:
    
    Well if it's still a problem for you then ether contact NG support and let them know about it or return it and find something that works for you.
