I'll pass the request onto the team but I cannot guarantee if/when it may be implemented. Did you enable UPnP again along with your port forwards? It could be a misreading so have you actually tried to host and had issues with people connecting?

i would to Feature Request an Addition of "Full Cone NAT" / "NAT Filtering: Open" Toggle The Problem is Currently, the Netduma R3 (DumaOS 4) lacks an explicit "NAT Filtering: Open/Secure" toggle. While the R3 supports PCP and UPnP, these protocols often result in a "Moderate" NAT type on PC for games with Peer-to-Peer (P2P) architectures, most notably Grand Theft Auto V. Symmetric vs. Full Cone NAT: By default, the R3 appears to use "Restricted" or "Symmetric" NAT filtering. While this is secure, it is incompatible with many P2P matchmaking systems. Even when ports (like UDP 6672) are opened via PCP, the NAT remains "Moderate" because the router only allows incoming traffic from the specific IP/Port that the PC first contacted. The "Full Cone" Requirement: For an "Open" NAT in GTA V, the router must support Full Cone NAT (Endpoint Independent Mapping). This allows any external host to send packets to the internal PC via the mapped port, regardless of whether the PC has messaged them first. Regional Necessity (Australia/Oceania): For players in Australia, the player pool is smaller. A "Moderate" NAT limits the number of successful P2P handshakes, leading to much smaller or empty lobbies, "Timed Out" errors, and increased latency. when playing with some other friends i previously had no issues with, since i had a router that allowed me to set Nat filter to open. An "Open" NAT is not just a label; it is a requirement for stable connectivity in isolated regions. The Solution here is I am requesting the addition of a "NAT Filtering" toggle in the WAN settings (similar to those found on Netgear, ASUS, and TP-Link hardware) that allows users to switch from "Secured" to "Open". because DMZ is not an answer: Using the DMZ is a "sledgehammer" approach that exposes the entire device to the internet. A "Full Cone NAT" or "Open Filtering" option provides the same connectivity benefits for gaming while maintaining a higher level of security by only affecting how active port mappings are handled. so for goodness sakes add this feature, it would actually help MANY people out with the multitude of complaints about Nat type open and especially for an issue like one console having open Nat and the other 2 having moderate or strict

The beta is no longer required as it is part of the latest public version now

add me!

No specific browser as long as you're not using Safari, every other browser as far as I am aware you can disable HTTPS redirects in the browser settings. Try both 192.168.1.1 / 10.0.0.1 or routerlogin.net just in case one works better than the other

You can enable UPnP, although you're correct it would avoid conflicts by keeping it disabled its quite unlikely to happen and I've never seen it cause any issues with both enabled and it may help you in this scenario. With that and the required ports it's unlikely you would actually have a moderate NAT even if its reporting it - have you actually hosted and had issues with people joining to check if it is moderate? If people can join then you will be open. Short of putting the PC in the DMZ which is a security no-go there aren't any other settings you could adjust to get an Open NAT. Do make sure to disable the Geo-Filter though as that could cause issues with people joining.

Which browser do you recommend? I can set the initial reset parameters, but when I have to continue in the router it doesn't let me continue.

I am trying to achieve an Open NAT in GTA Online (PC) to host lobbies for achievements. Despite a perfect setup, the game consistently reports Moderate NAT. Netduma R3 Firmware: v4.0.540 Connection: Direct NBN Fiber (FTTP) to NTD (No ISP modem/Bridge mode issues) Ports: All Rockstar-required ports (6672, 61455-61458 UDP, etc.) are manually forwarded. UPnP is disabled to avoid conflicts. I cannot find a toggle for 'NAT Filtering: Open' or 'Endpoint Independent Mapping' in the DumaOS 4 interface. It appears the R3 is performing Symmetric or Address-Restricted NAT by default, which is preventing me from being the primary session host.

The URL you're using to access is what I'd like to see as it looks like you might be trying to access the dumaweb part which is the mobile part of the interface. You may also be trying to access via HTTPS which wouldn't work well with the interface. Also the browser you're using would impact it because that may force HTTPS by default which again wouldn't work well. Make sure you're connecting via HTTP/the browser you're using has forced HTTPS disabled. The update has security fixes that's it, nothing from us or NTGR, no changes to DumaOS or settings etc so it would not cause any issues itself like this.

I have an internet connection, I can't log in to the app, the browser says "Duma is not running!" I've been stuck like this for a day, I restarted, reset and nothing. the image is the one above, you can't see anything else, I can't get in at all, the update you recommended to me blew up my router

The router doesn't have a way for you to look at what websites are being accessed at all or for a specific device and due to the way you have it setup the xfinity app will just see it coming from the R3 device, it won't be able to tell either so there is no way from what you're asking unfortunately.

Hi, i have a netduma r3 and i have it bridge with my xfinity modem/router. the xfinity app it keep blocking some sites that devices form my netduma is trying to connect, how i can see which device is trying to connect to those sites? Keep in mind i dont have any setting on adblocker activated. What im trying to figure out is what device from all the devices in my house is trying to connect to those sites. Thank you in advance.

As the physical setup has changed the same settings for QoS may not work as well so you'll just need to fine tune it more - don't rely on auto setup just adjust it manually - we usually suggest starting at 70% then adjust by 10% up or down (it doesn't always have to be lower) until you get to a value that's pretty good then try 5% either side of that value to see if it can be improved further. Download & Upload also don't need to be on the same percentage, you may have different percentages where they each give the best results. It is important you have set the speeds you pay for/expect into the router though so it's using that as the basis, otherwise if you've left it with the speeds the in built speed test came back with for example then you may have them set too low and then you're then making it even lower than needed with the percentages.

Thank you. I haven't tried gaming yet so not experienced any spikes. I used auto-setup on the QOS and enabled it as Always. It put download to 62% and upload to 100% I ran a Bufferbloat test and it came back grade D. I adjusted the download and upload to 60% each and got the same results on the test. Previously when using the PPPoE settings with the Draytek and same QOS settings I got grade A on the bufferbloat test (when the R2 was stable initially). Any ideas why it would have reduced to D, and if this means QOS isn't working correctly?

Yes that all sounds correct. If the issue is caused by the bridge mode/R2 using PPPoE then yes it would resolve those issues. The R2 firewall is constantly on, there is no way for a user to disable it, you are definitely safe in that regard. No you don't need to use a VPN. The DMZ just allows all traffic to pass through to the router unimpeded which is essentially what was happening by having the draytek bridged to the R2 so you would have been relying on the R2 firewall in that scenario as well. So far so good, you may need to re-fine tune your QoS settings but it should be fine as is, just monitor it and come back if its not quite right

Thanks for the clear instructions. I believe I have got it now. My current set up is Vodafone Power Hub plugged into power, DLS plugged into hub, Wan plugged into hub connecting into R2 Wan. Wifi on hub disabled. In hub 192.168.1.1 I've gone into the Static NAT/DMZ setting and enabled Exposed Host Function. My public IPv4 Address is my IP which I cannot change. My Local IPv4 Address is what I found on the Duma R2 in system information WAN IP. In the R2 I have the Wan connected to the hub. Ethernet into my PC. PC has successfully connected to the internet and my phone connects via wifi successfully. I can still edit the hub settings in 192.168.1.1 and can also edit Dumaos in 192.168.77.1 Does this set up sound 100% correct to you? Should this resolve my latency issues? How can I be certain that Exposed Host Function is safe and that the firewall on the R2 has enabled successfully? Would it be safer to use a VPN on 24/7 now that I have turned on Exposed Host Function, or will that not make any difference? Anything else that I need to change or consider? Thank you!

Can you provide a full screen uncropped screenshot please? That will help me determine why its happening

Yes switch to DHCP on the R2, you don't need to enter anything in any of the ID boxes there. The IP you need to put in the DMZ on the V hub can be found in two places, check one of these: On the R2 System Information page in the Network Status panel - it's right in the centre of the page On the V hub it would be the IP shown for it in Devices or LAN Settings. Wherever you see your connected devices on the V hub, whatever the IP that is shown for the R2 that's what you need to enter into the DMZ

current situation, reset, start configuration and then the router goes crazy

Sorry, this process is confusing me. I select DHCP on the R2 but then all the fields are blank. You told me I have to put the WAN IP of the R2 into the hub DMZ - I've found the DMZ field on the hub, but where can I find the IP that I need to put in there? Could you send me a screenshot of this please?

I got so many errors, now I can't log in anymore

What were the errors specifically?

I updated the router, everything worked normally, simple reboot: wait a few minutes to enter the router, various errors (from the PC it does not let me enter, the errors were given to me by the phone app)
