RBK752 - Awesome but disconnects on facetime a lot

Yes, then you will know if you are Double NAT'd or not

Is the EE router also inlcude a built in modem or is this just a router only? If this is just a router, is there a modem or ONT infront of this EE Router? 

Any luck with the tracert command?

On your EE Smart Hub, in the Hub Manager software you should be able to see this page

From the Home menu , go to Advanced Settings, then Firewall and then select Configuration. Look at the bottom of the page and yuo should see DMZ, if not please post a screenshot of what you do see

Hey
Before I do the above, I’ve now had 2 drop outs when directly connected to the EE router!

It took around 30 FaceTime quick fire calls but it did happen - does this change things?

Yes, if when taking the Orbi out of the picture you still have dropouts then you should fix those before looking into the Orbi settings.

Anohter way to verify if you have Double NAT is to compare Your IP displayed by http://canyouseeme.org against http://orbilogin.com / Advanced tab / Internet Port / IP Address. They will be the same if your Orbi is exposed to the Internet.  They will be different if you have Double NAT (you have another router exposed to the Internet and in front of the Orbi).

Here we go.... please tell me this tells us what we are looking for! :)

Thanks

This is a double NAT condition:

Were you able to find the DMZ on the ISP modems page as Foden mentioned? FT issue probably won't be resolved with Orbi or other wifi system until you can get into a single NAT condition at the modem, use DMZ or the modem can be bridged if possible. 

Yes, i see the exact page he posted with DMZ on it  -  what should i do?

You are Double NAT'd

10.0.0.1 is the IP address of your Orbi

192.168.1.254 is the IP address of your EE Smart Hub

Both IP's are within the Private Address Range

Follow FURRYe38's earlier post about DMZ

The reason i asked is when i turn DMZ on, it asks me to select a device - do i choose the IP of the Orbi? is that ll i do?

See msg #61 in this chain

Many thanks for that

10.0.0.1 is not showing in the drop down of all the IPs on the network

So it's only going to show you the 192.xxx.xxx.xxx IP range then, at least we have determined that you are double NAT'd

To clarify, you are able to get to the the web address of each router 10.0.0.1 and 192.168.1.254 from the same device, like a PC?

Also, 192.168.1.254 is not the default IP address for the EE Smart Hub, I believe it is 192.168.1.1

Not sure if this will work, but worth a shot

Is your EE Smart Hub setup as a DHCP server? If so, turn OFF DHCP and change the routers IP address to a static IP of 10.0.0.1

On the Orbi router turn ON DHCP, if its off, and set the router to have a static IP address of 10.0.0.2 and adjust the IP range it provides to start from at least 10.0.0.3

e.g.

10.0.0.1                EE Router            Static IP                 DHCP Off

10.0.0.2                Orbi                       Static IP                DHCP On

That puts all your devices on the same IP subnet – may need to tweak other settings but give this a shot

If it doesn’t work take screen shots of the settings you changed on the EE router and those on the Orbi, as well as the Internet Setup Page

👍

Hey,

yes i can get to both of those addresses from the same machine

Hey, if followed the guidance and changed the DMZ to on and selected

192.168.1.92 RBR, This is the IP address i found on the orbi page which is labeled as "internet port" on the advanced section - so ive put this in the DMZ section on the EE router and disabled both wifi radios

I have ran the below again and it looks the same to me?

Tracing route to google.co.uk [142.250.187.195]
over a maximum of 30 hops:

1 6 ms 4 ms 4 ms 10.0.0.1
2 5 ms 4 ms 6 ms eehub.home [192.168.1.254]

10 21 ms 20 ms 21 ms lhr25s33-in-f3.1e100.net [142.250.187.195]

It will look the same for a trace route. DMZ won't change how the trace route results. That will still see the router and ISP router/modem in the line. 

ok, how do i know if the double NAT is fixed? I just tired facetime and it disconnected on the first attempt after making the change

on the EE page there is a setting to turn on "Enable SIP ALG" this is currently off

So still happening. 

Seems that something with your ISP modem is problematic with putting a external router online with the ISP mode and even using DMZ, something is still failing for FT...
