Help with Hub 3 setup with Eero

[iturnbu11]

I have FTTP and moved to pure data contract and given up copper for phone.

I have a 4 Eero setup in a alrge hosue and use prot forwarding and love the eero app.

However to get the phone to work of fibre, I got sent a hub 3 router.

I have put this in fron to fth e primary eero.

I have used a static ip for the first eero and used hta IP in the hub 3 as reserved and placed it in the DMZ.

I problem is the hub 3 disconnects the eeros after about an hour or 2. They get a red light (no internet).

Rebooting the hub 3 resolves the issue.

I spoke to support and they would not send me a voip adapter so I have to make the hub 3 router work.

Is the issue the DMZ and the hub 3 DHCP lease confusion? 

I have already disabled UPnP on eero

I use 8.8.8.8 for DNS

Am now nw looking at putting eero in bridhge mode and having the hub 3 do the port forwarding ?

thanks

Hi @iturnbu11 

Is your FF provided by CityFibre? They are not like OpenFReach and before you can connect an eero directly to the ONT you need to get the CityFibre line profile set to T. If you want to do that, contact the Full Fibre Helpdesk via the link in my signature.

To use the Hub 3 with port forwarding requires that it be configured thus, because you have created a Double NAT scenario. The Hub 3 is on a different IP network from the eero, assuming that it is using the default IP address configuration. With the WAN port of the hub 3 connected to the ONT, the Ethernet connection from the Hub 3 is now the eero's WAN link.

Configure the port forwarding for each port in the hub 3 to point to the WAN IP address of the eero, that has been allocated to it via the hub 3. This will, by default, be 192.168.1.x. Now, in the eero, the existing port forwarding should be OK. 

Any problems, let me know.

Did you specify you wanted VOIP to keep the use of the landline number at the time of ordering?

Was this previously copper leave behind, so you had Full fibre already installed, using Eeros previously?

It's not very clear from your post.

Normally you would now only be sent the Hub3 but VOIP definitely needs to be included in the package. Extenders usually help sort things if the wifi doesn't reach well - not Eeros with the Hub3.

Yes as stated I have dropped copper and jsut have FTTP (fibre to the property)

[KeithFrench]

So you don't have full fibre?

Hi Keith 

Thansk for the reply.

Thats what I had before I had to move the phone from the master socket (copper) to the fibre (voip) conenction.

There is no phone adapter on an eero, so I had to put the hub 3 in the loop to plug in the phone.

I would have prefered a voip adapter that was dumb.

Adding in the hub 3 at the front I have to DMZ the eero to allow traffic to go straight to it.

But the fact that the Hub 3 drops the DMZ devices every couple of hours is a pain actually worse than tha.

I feel i can only get th ehub 3 to do the routing now and have the eeros in bridhge mode, but the other way should work, but the hub 3 is too unstable.

You do not need the Hub 3 at all for this. Just connect your gateway eero to the ONT via Ethernet.
