I've given you Early Access where we've recently released a fairly large bug fix/QOL update that may help. https://forum.netduma.com/topic/60946-new-r3-firmware-dumaos-401147/ Upgrade to that and then if you still get the issue please get the logs when the issue next happens, before rebooting and we can take a look.

Very bizarre! Perhaps their servers were under heavy load at the time. Thanks for the update!

You shouldn't need to specifically port forward but if you look up the specific games you're playing you can find their specific ports to add

Hi Netduma Support, I’m experiencing an issue with my Netduma R3 where the Ethernet ports stop working after about 1–2 days of uptime. Here is what happens: The router works normally at first After 1–2 days, all devices connected via Ethernet lose internet access WiFi continues to work without any issues A reboot temporarily fixes the problem, but it comes back again after some time I have already tried the following troubleshooting steps: Updated to the latest firmware version Performed a full factory reset (without restoring any backup) Set up the router from scratch Tested multiple Ethernet ports Tested different Ethernet cables and devices Disabled IPv6 Increased the DHCP lease time to 10000 The issue still persists consistently. From what I can tell, it seems like either a DHCP issue or a software-related problem, since a reboot always restores functionality temporarily. Could you please advise on what might be causing this and if there is a fix or known issue? Thanks in advance.

Here are my results today — 10:47 AM, April 21, 2026. And the next day it looks like this… everything is kinda weird.

Yeah, Fraser, you were probably right. I checked this morning and everything’s fine. Yesterday it was messed up, now it’s normal. That site is just buggy as hell — screw that site.

What port other than 3075 fo pc/Xbox Game pass should i have?

They shot first. I still won the fight. Playing on East Coast servers from the West… still outgunning like this. 🎥 Watch it here 👉 https://youtube.com/shorts/2FnZuO-Lm3Y?si=-S97OeHoOpgN90VF — 🔗 All Platforms, Links, & Setup: https://toddzillainla.carrd.co/ 💬 Discord: http://discord.gg/zillagaming (if link is dead, add me @toddzillainla and I’ll send you an invite) Or watch here 👇 Thanks for watching! 🙏🎥❤️✨

If speedtest.net is showing your normal speeds then the router isn't limiting you but try toggling speed test bypass in Ping Optimizer > Advanced. Otherwise it's unlikely there is any feature impacting it and is more likely the site.

Hi, I’m experiencing a strange issue with my NetDuma R3 and wanted to check if others have the same problem. When I run a normal speed test (e.g. Ookla Speedtest), I get my full speed: Download: ~220 Mbps Upload: ~40 Mbps However, when I run the Waveform Bufferbloat Test: Upload looks normal BUT download drops massively to around 10 Mbps This is a huge difference (more than 20x lower than expected).

You can't individually filter a cluster of servers within one location per se but you could add the 17ms ping server to your deny list so you don't play on it again. Do be warned though that denying lots of servers will leave you with very few options for servers to play on and may increase search times/prevent you getting a game altogether.

Are you just focusing on the jitter result on the bufferbloat test or are you actually experiencing that in game also?

Hello! I was able to get my geo fence working and pining exact cities etc. I am now wondering how I can ping the best “server” in that city. For example I saw a Chicago server on 6 ping but connected to a different Chicago server with 17 ping. Is there a way to get only that 6 ping server?

if I connect the other router I have A+ without problems

So the fiber router connected to the R3? For the Geo-Filter you're covering a huge area so you could be getting servers that are a way higher ping, reduce it so you're covering just the closest server to you. Just on SmartBOOST, add Gaming as the activity, then switch to device on SmartBOOST and select your device.

No, I don’t have other devices heavily using the internet. My setup is: I have a fiber modem connected to the Netduma R3 using PPPoE. The R3 is used only for my PC. As for the main fiber router, it only has two iPhones connected to it. My internet speed is 300 Mbps download and 100 Mbps upload. Regarding the Geo-Filter, since I’m located in Saudi Arabia, the closest server I get is around 20 ms ping. I have enabled Steady Ping and set it up in a simple way like shown in the screenshot. About Congestion Control, I understand that having it at 100% doesn’t help. I will try setting it to 75% download and 68% upload and see how it performs. I have already removed the 40 Mbps bandwidth allocation after writing this post, as I’m trying to fully utilize the R3 in the best way possible. Regarding these two points, I haven’t set them up before, so I would appreciate it if you could explain how to do them, preferably with screenshots: Enabling “Prioritize Gaming” globally (so it covers all games) Prioritizing my PC as a device as a backup

It should be easier to filter BF6 on the new R3 Early Access firmware now

Here's what you need to do. Google the ports for bf6 for your respective platform. Give your device a static ip address. Add those ports in port forwarding to that ip address so the you can authenticate with the game servers. Make sure game is closed and process ended in task manager if youre on pc Remove device from geo filter. Flush the cloud. Restart the router from the interface. Add device to geo filter use as normal. I will try to match you a server outside your filter but it will just stop searching. After it stops just start again

Just to clarify, you said your modem is in bridge mode and the R3 is in its DMZ - it can only be one or the other, which one are you using? By the only device being connected to the R3 is the PC do you mean you have no other devices in your home using internet or that they are connected to a different router? If the latter could you explain how they fit into the network please. How have you enabled the Geo-Filter exactly? Currently you're not using Congestion Control with it set to 100 so that won't be helping. Try with 70% and experiment from there to find what percentages work best for you. You've reserved bandwidth for certain games (gaming barely uses any bandwidth so 40Mbps is overkill and won't get anywhere close to needing that much so you could remove this) but then you haven't prioritized those games. Prioritize Gaming overall so it covers all the games you want to play. Also prioritize the device as well as a backup. Is the PC the risk device? In which case you should absolutely remove the DMZ rule and the port forwarding rules as it's a major security issue for PCs. If it was a console however the port forwarding rules would be unnecessary because its in the DMZ already.

The only way that makes sense is that the routing from you to the game servers is poor, in which case no router could resolve that, it'd be something you'd need to go to the ISP with but they would be unlikely to help

Hi, I’ve been using the Netduma R3 for about a year and a half, but I feel like I’m not fully taking advantage of it or setting it up properly. My current setup: Fiber modem is set to Bridge mode DMZ is enabled to the Netduma R3 The only device connected to the R3 is my PC Geo-Filter is enabled and in use UPnP is enabled Despite this, I feel like I’m not getting the best possible performance. My questions: Are there any essential settings I’m missing besides Bridge mode and DMZ? What’s the best way to configure Congestion Control? Is SmartBOOST useful, and what are the recommended settings? Are there any commonly overlooked settings that could improve performance? I’d appreciate any guidance on how to fully optimize the R3. Thanks.

If I remove the PC from the DMZ of the Duma I will no longer have NAT open, the fact remains that with all the "solutions" I have tried the download jitter always remains 15-50, with VPN it returns to 2ms

You'll need to give us the ID of that server then we can correct its location in the cloud. Until then you can add it to your denied list to prevent connecting to it. You should never put your PC in the DMZ, it's a major security issue, I would strongly suggest you remove that. It could also be impacting your results but also with your configuration the router can't properly control devices individually to prevent issues.

That's what happens when r3 gives good ping and stable connection!

MK35 ISR… no recoil on this one. Playing on East Coast servers from the West, 80 ping… still beaming like this. 🎥 Watch it here 👉 https://youtube.com/shorts/T-O2ALx5KXM?si=yP2-CDx24xlK-NSi — 🔗 All Platforms, Links, & Setup: https://toddzillainla.carrd.co/ 💬 Discord: http://discord.gg/zillagaming (if link is dead, add me @toddzillainla and I’ll send you an invite) Or watch here 👇 Thanks for watching! 🙏🎥❤️✨
