Create seperate network

[hobro]

Actual setup:
VDSL Router (Vodafone NZ) with DHCP for internal network 192.168.1.xxx . This router also provides a wireless guest network. Two Airport Extreme in Bridge mode and a "private" wireless network. Nevertheless, as all devices in the same IP range, guests can access hardwired devices (printers, home automation) in the network.
Question: is it possible to setup one of the AE as another router with an external address 192.168.1.? and an internal network range 192.168.2.xxx and DHCP? The 2nd AE could still run in Bridge mode in the 192.168.2.xxx range.
Any advice would be much appreciated!

Technically, you can do that with the devices you mentioned, but you end up with double NAT. This causes issues with various services and can be troublesome. I wouldn't advise it.

You can use different gear to do this, such as Ubiquit's EdgeRouter, and setup a proper firewall and routing.

If you are considering new hardware, lots to choose from that can give you a full fledged, manageable guest network.

Besides an Edge router, which is a steep learning curve for a home user, and is primarily marketed to network professionals (I have one), other options include Access Points (not a full router) such as UBNT Unifi APs, which have lots of features and options, but are fairly easy to manage. You can have a landing page for guests, and even charge them.

Easier still: Synology routers are very full featured, and have a solid, yet easy-to-configure guest network setup.

There plenty more to choose from too.

What are you trying to achieve?

In general, you'll run into problems not being able to add routes to this type of device.
