The Huawei B315 LTE router limited LAN-side networks to the 192.168.x.y range.

Is this limitation present in the B618?

Asking because the customer's LAN is 10.0.0.0 and I don't want to reconfigure PCs, printers, POS devices, etc, etc, to fit.

Thanks

Scott

Unless it's been locked out most should let you.

Either under the DHCP scope settings you can get reconfigured, or changing the default IP of the router will do so - automatically updating the DHCP lease range to match x.x.y.y

Yeah, I need to know for this specific router. It wasn't possible on the B315 to use anything outside 192.168.x.y on the LAN.

That would be expected if you had fixed IP devices outside the DHCP scope (not NATable) but didn't reconfigure the management IP first.

Seeing a few mention DHCP scopes on B315 here and not specifically referring to being too locked down...

You cant' get to settings-WLAN and see the top IP specified? (it doubles as the management IP of the router)

Adjusting that to 10.0.0.1 would in turn fire up the same DHCP ranges and allow devices within that range

It'd suck if they've been dumbified beyond that :)

That's exactly what they have done with the B315. Fingers crossed that the B618 isn't the same.

I've got a B618 running at a remote house, and I just checked for you (as I can access it via OpenVPN to a raspberry pi), and the LAN is limited to 192.168.x.x, as per screenshot below.

This B618 is from Skinny, full model number is B618-65d.

Let me know if there is anything else you want me to check on the B618.

If you are really set on keeping the 10.0.0.0 LAN, just use the B315/B618 as a gateway, and put a better router behind it, that will allow more flexibility, routing, etc.

So the trend I'm seeing here is

ISP 'Apply custom FW and stop people potentially breaking it and making helpdesk calls' so for most it just... works

While a standard FW would probably leave it unlocked.

Cloud spending continues to surge globally, but most organisations haven’t made the changes necessary to maximise the value and cost-efficiency benefits of their cloud investments. Download the whitepaper From Overspend to Advantage now.
