Ya yes, NG and Linksys are not good for supporting of local DNS side addresses. Kind of a shame.

I just got the TP-Link C5400X and it does support local LAN side custom DNS. Which is nice. :dance:

Unfortunately Port Address Restricted is the NAT kind. I'm still checking to see if there is any FULL CONE NAT support. :think:

Other than this, seems like a nice router. Will be doing some two xbox gaming with it and see how it goes.

Got the RT-AC86U configured today and UPNP + Full Cone NAT and finally I have Open NAT on all Windows 10 clients, in CoD: Black Ops 4 on all clients while playing the game at the same time and on all the consoles!

Boy the list is growing with more and more new fails! I am fearful for upgrading past AC (AX/Wifi6/etc) as it seems like every new router fails to provide open nat with 2 xboxs. Part of me really wants to move on from the XR500 but I am clinging on to Full Cone NAT for dear life :XD:

After weeks and weeks of research and unwillingness to get rid of x86 hardware, I finally got full cone NAT working on OpenWRT, I had to create a custom build of OpenWRT, but once done I got it to work. I had to set up an Ubuntu VM as my build server to create the custom build, flashed it to a hard drive, popped it into my server and now I get full cone NAT on OpenWRT. Would definitely prefer running pfSense, but no matter what you get stuck with symmetric NAT. OpenWRT is a great alternative! Plus the QoS is awesome too!

Was curious if anyone could get FULL CONE NAT on WRT.

Is there a process or do you have a specific build repo for other users to check out? I presume you built a version specific for a certain mfr and model router you installed it on?

Yes, I built the x86 version and installed it onto a server. But like you said, this would open up full cone NAT for A LOT of routers since OpenWRT works for many different routers. The only catch is that you need to do a custom build. I’m working on a video tutorial, but I will also push up my repo which will have my .config file and the x86 images pre built.

Ok, this is kewl. Thank you for posting this and making a video for those who wanna dive in to this.
There is only one router mfr left that allows FULL CONE NAT on some of there routers. NetGear.

Will be helpful to have an alternative source though with WRT. ;)

The Asus RT-AX88U is rock solid with Asuswrt-Merlin firmware. It's one of the very few models that come with the option to configure Full-Cone NAT directly in the firmware if you run Merlin's firmware on it.

The downside is the Broadcom WiFi chipset as it's one of the poorer ones so you don't really get any stellar 802.11ax/WiFi-6 from using it. But it has a rather capable quad-core ARM CPU and plenty of RAM so in terms of performance you get pretty much anything you would ever need for a 1/1Gbps connection and you'll get fully working full-cone NAT.

I'm not using the WiFi. Mine is a router-only, my WiFi is using Ubiquiti UniFi AC HD access points. And as my WiFi is running separate I'm able to replace the access points when Ubiquiti have some 802.11ax/WiFi-6e ones available and not mess with my full-cone nat setup.

I'm not entirely sure why only such limited amounts of Asus models supports full-cone nat. According to Merlin, it's because of the SDK's. It's only Asus RT-AC86U and Asus RT-AX88U that allows for him to make the option available.

Ya ASUS SDKs are limiting and they seem to keep the GT series only available to stock FW. Merlin doesn't seem to be able to develop FW for any GT series routers while RTs are more open to 3rd party developers. :think:
