No IPv6 on Netduma R3 Xbox Series X & Packet Loss (Xfinity Router/ISP)

[traximilian]

Hi Netduma Fam,

I am looking for some answers on some questions I have on my Netduma R3 and Xbox Series X setup I currently have going on. Please see below:

 

Question #1 on IPv6:

I have an Xfinity XB7-T router hardwired with an ethernet cable to my Netduma R3. The Netduma R3 is DMZ'ed on the XB7-T Xfinity router via the WAN IP. I have my Netduma R3 hardwired to my Xbox Series X with the CAT 6 ethernet cable that was included with the Netduma R3.

When I have my Xbox Series X hardwired into my Netduma R3 my Xbox Series X shows the Current Network Status as follows:

- Wired

- IPv4

- NAT Type: Open 

 

When I have my Xbox Series X hardwired only into my XB7-T Xfinity Router my Xbox Series X shows the Current Network Status as follows:

- Wired

- IPv4 & IPv6

- NAT Type: Open

 

• How do I set up my Netduma R3 so I am able to get IPv6 on my Xbox Series X like I am directly through my Xfinity XB7-T Router (my ISP)?

 

Question #2 on Packet Loss:

 

When I have my Netduma R3 hardwired to my Xbox Series X and run the "Test network speed & statistics" it shows "100% packet loss". 

 

When I have my Xbox Series X hardwired to my Xfinity XB7-T Router and run the "Test network speed & statistics" it shows "0% packet loss."

 

• How do I set up my Netduma R3 with my XB7-T Xfinity Router and Xbox Series X to not show or have any packet loss? I am noticing ping fluctuation and loss of voice comms in certain games and I am not sure if these are game server issues or if I am actually experiencing packet loss?

 

I am happy to set up any additional tools or run any other tests to get more information. Additionally if I need to post screenshots of the UI elements I am describing above listing network parameters please let me know. 

 

Thanks,

This is not possible with your current configuration unless your main router supports IPv6 prefix delegation. The Comcast modem does not support this. Essentially, your issue is related to the cascaded router configuration (Netduma behind the Comcast modem). With this configuration the Netduma router is not on the same subnet as your Comcast modem, so IPv6 for the internet won’t be available on your Netduma devices. Keep in mind that with 2 routers you have two networks. Your ISP provides an IPv6 address for your home network where a portion of the address space could be delegated to another network. The problem is that the Comcast modem doesn’t support this type of configuration.

I was able to get IPv6  prefix delegation working with Comcast with a cascade router configuration;however, I’m using my own router instead of a Comcast router which is opnsense based and supports IPv6 prefix delegation.

Google “What is IPv6 prefix delegation”

Sounds like you have a good answer for part 1 above. For part 2, do you have the Xbox added to the Geo-Filter at all? If you remove it and then test again do you get the same issue?
