I have Fttc broadband. What changes must I make to my smart hub 2 to be able to use my ASus router and how do I do it?

Thanks

What do you actually want to do? How do you propose to connect your router, LAN to LAN or LAN to WAN?

Do you need to use the hub at all, it is only required if you have Digital Voice.

Is the Asus a router as posted or is it a modem/router? If just router then you need use the hub or obtain a separate modem

Hi.

its a router with LAN. I have digital voice, so I need the smart hub. I’ve tried looking to adjust the smart hub so I can use it as a modem and use my ASUs as a router, but can find anything. All by devices are connected to the asus. (ROG Rapture GT-AX6000). I hope this helps?

Thanks

ps. It’s not full fibre just fttc

Not quite sure what happend the first time but the first reply disappeared into oblivion. So, I'll try again...

The SH2 needs to be directly connected to the phone socket for digital voice. I did mine this way:

Smart Hub 2 (SH2) router settings:

DHCP off. (The addresses here are best set as static addresses).

Router itself set to a static IP of 192.168.1.254, (the default).

Subnet mask of 255.255.255.0 or /24, (also the default).

DMZ host set to 192.168.1.2 (This helps with double NAT problems or at least it takes care of the port forwarding on the SH2. There is still address translation happening, however, so you may still have problems with multiplayer games, UPnP etc. In fact, you only really need this if you have incoming external connections to a server etc. Personally, I’ve never found double NAT to be an issue and I don’t use the DMZ setting. Note, this setting allows a lot of traffic to effectively bypass the SH2 firewall, so you are relying on your own router’s firewall for security, just as if it was directly connected to the internet).

Turn off both Wi-Fi bands in favour of your own router. (This may also be a good security move if you do enable the DMZ host. I would still expect Wi-Fi traffic on the SH2 to go through its firewall but I can’t be sure how they’ve set it up internally).

Connect the DSL port to the phone socket on the wall, (or the WAN port to the ONT, if on FTTP).

DV phone/extension then plugs into the phone socket on the Smart Hub 2.

Own router settings:

DHCP on, range 192.168.0.2-192.168.0.200 (Note the 0 in the third position, making this a separate network to the SH2. This is deliberate, not a typo).

Router itself is on a static IP of 192.168.0.1

Subnet mask of 255.255.255.0 or /24

Enable the EWAN port and set it to a fixed IP of 192.168.1.2, (so it is part of the SH2 network).

Gateway set to 192.168.1.254, (again, pointing to the SH2).

DNS set to 192.168.1.254 (or whatever you usually use).

The EWAN socket on your own router (probably 4) connects to a LAN port on the SH2. (NB. This will not work if you use the DSL port on your own router).

I would just add that you should DISABLE the wifi on the SH2 so turning off the BT/EE Wifi.

Posting this to try and make things a little easier and closer to Asus conventions.
So follow everything in the previous post until you get to the Own Router Settings part, and you'll need to run a cable from the WAN port of the GT-AX6000 to a LAN port on the SH2.

On the Asus router:

WAN > WAN Internet connection:

Basic Config: WAN Connection Type > Static IP

WAN IP Settings >

IP Address: 192.168.1.2
Subnet Mask: 255.255.255.0
Default Gateway: 192.168.1.254

WAN DNS Setting >

Assign: 8.8.8.8 & 8.8.4.4 or 1.1.1.1 & 1.0.0.1 or similar, ideally don't point to the SH1 gateway , this will allow the Asus router to cache DNS responses.

LAN > LAN - LAN IP>

IP Address: 192.168.50.1 *current Asus convention

Subnet Mask: 255.255.255.0

LAN > DHCP Server > Basic Config >

IP Pool Starting Address: 192.168.50.2

IP Pool Ending Address: 192.168.50.254 *you can reduce this is you need to reserve any addresses

*if you really want to use the BT DNS servers bypassing the DNS cache on the Asus router

LAN > DHCP Server > DNS And WINS Server Setting >

DNS Server Setting 1: 192.168.1.254

Advertise router's IP in addition to user-specified DNS: NO

Once it's up and working you can have a play with the many more settings!

@Crimliar Yes, the use of 0 was just generic, trying to keep things simple. I actually use 144 myself but I won't go into the reasons on here. He can use whatever he's currently using, rather than redo any static assignments he already has, so long as it doesn't clash with anything.

@TimCurtis I thought I said that?

@WSH Most of the Asus help, now uses 192.168.50.x for some (random) reason - I've used random/prime numbers for that third byte myself in the past too. At least setting up IPv6 should be a breeze, as "Passthrough" should work just fine! Personal opinion on my part though is that Asus routers don't handle double NAT as well as some of their competitors!

*Current config here: 900/100 FTTP : Asus GT-AX6000 (Merlin firmware): Asus RP-AX58 : TP-Link SH1008
