What is better for me?

Hi all, 

I recently got my Eero 6 (1 gateway + 2 nodes). It is connected to an ISP modem/router. I'm facing the following problem. When using the Eero as a router I can't use ipv6 and I have double NAT (I can't bridge the modem/router unfortunately). When using the bridge mode on the Eero, I don't have double NAT and I can use ipv6. Do you think it's worth it to run the Eero in bridge mode or not? Also, will SQM (when it's available) be compatible with bridge mode?

  • Hello OG_Metapod ,

    Ideally, you want to use the eero network and not in double NAT. Does your Modem Router Combo have a DMZ setting? If so, you can place the Gateway eero into the DMZ and could work. SQM, when it becomes available for the eero 6 models will not be able to be used if the eero network is in bridge mode. Here is a link that shows all the settings that you access to when the eero network is in bridge mode.


    • James I did try to put in DMZ, but I still get double NAT. 

    • Hello OG_Metapod ,

      It is possible that your ISP handles the NAT upstream. I would suggest giving our support a call at this point so we can take a look at your network and gather more information to give you the best possible solutions. I have included a link below that you'll be able to find a good phone number to call for support.


    • James Thanks for helping! I will look into it. 

      In case there is no solution what do you think will be better? Router mode with ipv4 and double NAT or bridge mode without double NAT and with ipv6? 

    • Hello OG_Metapod ,

      This is not something that is easy to answer. I personally run my eero in double NAT and have done so for a year without any issues. I am doing it more for testing though. Ideally you want your eero to not be in double NAT. The eeros can work fine in a double NAT, but devices connected to that eero might not work okay in a double NAT. In regards to the IPv4 and IPv6 question, that is up to you. I would research what IPv6 offers and see if that is something you think you need. I am personally fine with IPv4. It works great! Plus I don't have any devices that can really make use of IPv6. So I don't use it. 

      I know this isn't the concrete answer you were looking for but everyone has different devices with different needs. So it is difficult for me to say that you should do x or y. All I can really say is research the devices in your home, do they support IPv6? Check with the manufacturers as well. Run some tests with the network setup both ways and see which you prefer. 

      Something to keep in mind is that IPv# is just an addressing system used to help devices connect to a router and communicate to the web. 99% of customers will be fine with IPv4 as the primary reason to switch to IPv6 is if you are running out of IP addresses to assign to devices on your network. Eventually IPv4 will be phased out, but that is still years in the future. So it really comes down to personal device needs/capabilities and preference right now.
