Smart Hub Plus ipv4 configuration

[David-A-James]

I've just moved to EE's FTTP from Plusnet's FTTC.

I'm trying to configure an (internal) ipv4 addess for the new Smart Hub Pkus to an IP address which is not in one of the private IP address ranges. This doesn't seem to be possible (Error message "The Hub IP address is not a valid privaye IP address") - is setting an IP address outside the private IP address ranges not allowed?

This is the way that I had my Plusnet router configured (this set up goes back many years through many ISPs back as far as Demon Internet).

What about it? It's already defaulted to a sensible config.

I have several internal devices with static IP addresses in the other address range - I'd rather not have to change all of them (plus internal DHCP servers).

Is the answer that I can only configure the Smart Hub Plus with an address in one of the private IP ranges (which is what the error message appears to be saying)?

@David-A-James   what service have you moved to - speed?

Which PN router were you using?

As with most BT/EE routers these days there is very little you can change from standard, however it may be possible to simply use the PN router simply by changing the Username and password on the PN router.

Yes. If you want devices to keep in another DHCP range you would need to set up another subsidiary router with DHCP handing out that range & connected by its WAN i/face.

Or you could change the DHCP range of the SH+ to a Custom range accommodating that other range.

I don't know what the Plusnet router is, but I can't keep using that as I need to retirn it to PlusNet.

The Smart Hub Plus (SH32B according to the label on the bottom of it) won't allow me to set the "Server address range" in the DHCP Server settings to adresses outside the private IP address ranges - you can set the server address range to "Custom", and type in start and end addresses, but when trying to save the settings, the error messages are "The Hub address is not a valid private IP address" (even though I have left that as 192.168.1.254), "The DHCP start IP address is not valid" and "The DHCP end IP address is not valid".

However, if I first disable the DHCP server on the Smart Hub Plus, and reboot the Smart Hub Plus, I can then set the hub's (internal) IPv4 address to the address I want (and that has been retained after a reboot of the hub).

So I think I am now where I wanted to be - the Hub now has the internal IP address that the PlusNet hub used to have, and the DHCP service is now only on my local DHCP servers.

Next step is to configure all the port forwarding that I had previously ...

That is what is preventing you setting a Custom DHCP range. You have to 1st set the router's Gateway IP to fit in with the range you want. Otherwise the Custom range you set will not fit in with router's Gateway IP. Hence those 2 invalid msgs.

[David-A-James]

If I try to set the hub's IPv4 address and set the custom DHCP IP range at the same time, then I get the three errors I have posted above.

It may be that the sequence: turn off DHCP, reboot, set hub's IPv4 address, reboot, turn on DHCP, set custom start and end of DhCP range, and reboot again, might work - I've not tried that.

But attempting to set a non-private IPv4 address for the hub and matching DHCP start and end addresses in the same step does NOT work.

What exactly do you mean by 'non-private IPv4 address'!? The LAN interface of your Plusnet/EE hub should never be assigned a public IP address. Perhaps you can share what IP addresses/ranges you're actually trying to configure and why? If you have your own DHCP server then why are you trying to also configure DHCP on the hub?
