This morning I installed a ConnectBox3 in place of my previous ConnectBox2 which was in bridge mode connected to a Synology router.
After installing the new CB3 I recognised it is in Router Mode & in the options there is no DMZ.

For a standard home user, are there any benefits to stay with IPv6 or should I request to be changed back to IPv4 ?
If I stay with IPv6, does anyone have an suggestions for how to setup the CB3 & router ?

I was thinking to leave CB3 to assign 192.168.1.x address to the router & then the router to assign 19.168.0.x address to all the devices?
However, with no possibility of a DMZ, will I not have problems with a double firewall ?

I also noticed that I cannot change the CB3 setting so it can only assign 192.168.1.x address (is this also a limit of IPV6) ?

I initially thought that this configuration was working as some devices seem to be connecting to the internet.
I have deactivated the “Firewall” in the CM3 settings & left the Synology router configured as before.

Xbox works fine with an IPV6 address as does my Windows PC.

However, I have problems with many cloud detected devices, Sonos, iRobot & even my phone “wifi” internet connection is not robust. I can connect to the devices after 3 or 4 attempts but after a few seconds/minutes they are not longer connected.

Hello @Gabbo
Thank you for your message.

Do you still want the changeover from IPv6 to IPv4, or would you like to leave your box in the current configuration?

Kind regards,

Mattia

Hello Mattia, I have already been changed to IPV4 and configured bridge mode….
Everything is working fine & exactly like before with the CB3…

I dont really know what the difference is for a “home user” to use IPV6 vs IPV4…
Most of my devices were working as expected but I had some problems with some cloud connected devices losing connection temporarily or requiring several attempts to connect e.g. Sonos & iRobot….

What am I losing by not having IPV6 ?

It seems strange the configurations for internet speeds >1Gbps do not allow the user to easily use their own router for Wifi…
I prefer to have my own Wifi router because Sunrise dont offer the advanced capabilities such user access, monitoring or notifications when a device connects to your network.

Why was the DMZ feature removed from the CB3?
From what I understand from the forum, if this was activated again, users could have IPV6 and no problems with double NAT…?

Anyway, everything is working for me so I am happy.
But considering that I paid for the “upgraded device” to 2.5gbps I am surprised at the lack of information in advance…..
You could ask the users when taking the new CB3 of Fiber if they will use their own router & automatically configure it as IPv4 from the beginning… Or inform about the need to switch to IPV6 or provide advice has to avoid the double NAT etc.

Gabbo Our modems are all sent with IPv6 DS Lite. This protocol is sufficient to consume the Internet with most service providers (Apps, Streaming, etc.). The DMZ mode does not work with IPv6 DS Lite. However, if you have devices that need to be accessible from outside, cloud services, gaming servers, etc., we recommend the IPv4 protocol in case of problems.

If you use the bridge mode, all protection functions and the WIFI on the modem are deactivated, as we assume that your own router takes over the NAT and WIFI function. You can therefore set up the network you want with the bridge mode and your own router.
