NAT Hairpin/Loopback
This thread has been locked for further replies. You can start a new thread to share your ideas or ask questions.
Hi all,
Ok so I thought it was a case of either supporting it or not supporting it. But for some reason the Deco seems to "kind of" support it , when it can be bothered.
To give context of what is happening , I have a bunch of web cameras which I access from my mobile device (phone) on a regular basis. Each one is accessed via a DDNS domain name and NAT'd on my router using port forwarding (ie incoming connections to router IP address on port 8000 is forwarded to 1 camera on port 80, and 8001 is forwarded to a different camera on port 80 etc.
With my old router I used to do this and it worked absolutely fine when accessing these either internally or externally from my home network.
I've now got the Deco as a router and have set up forwarding the same as before, but connectivity to the cameras when I'm inside my network sometimes works, sometimes doesn't, and when it does, it is hideously slow.
I've tried disabling the IPS etc on the Deco to see if it was that, but alas it makes no difference.
Pretty sure I can't be the only person with a Deco that is wanting to do such a basic thing like this.... help?
Does it support it or not?

Well the "next firmware' has come out but there is no mention of this in the change logs , so I guess 3 months wasnt enough for them to add it to this release (?!?)

This issue is really limiting for me. When will the updated firmware be available for the Deco P7?

Hi all,
The NAT loopback issue has been fixed via the latest firmware.
You can give it a go with QoS disabled to verify the performance.
Any updates, please let us know.

Are you not able to access the local network with the internet IP and port number? Could you please show us a picture of the ping result?
Meanwhile, please ensure that QoS has been setup as standard; try to disable antivirus and remove all the high priority rules.
Any updates, please let us know.

Hello again.
After setting QoS to default, and removing all devices from the high priotity list, the port forwarding has worked as expected for me.
Thanks for the help.

I suffer from this issue on the Deco M9 plus V2. I have spend multiple hours trying to find a workaround for this.

I've found that loopback works very poorly with high priority settings. Why are these features mutually exclusive? Is there any way to make them work well together?
Without high priority, loopback works as expected. With high priority, it tries to work, but it slows the loopback traffic to such a crawl that it might as well not work at all. It will appropriately resolve the correct LAN IP, but even simple html pages take minutes to load. As soon as I turn high priority off, it's blazing fast again.
Why can't I use both of these features at the same time?
