R6230 Create subnet of main network

R6230 Create subnet of main network

Model is R6230. I wasn't able to enter that as the model.

 

Current Configuration:

FIOS modem --> Juniper Firewall --> Large Ethernet Backbone -->  Several Apple Airports

The Connections to the Ethernet Backbone require static IP addresses (DHCP not distributed).

Each Airport distributes via DHCP a specific subset of the network IP addresses.

 

What I am trying to do:

I am trying to setup a R6230 at a remote part of the property.

The R6230 will be connected to the Ethernet Backbone.

The Internet Connection will be Static IP.

 

Preferred Option 1 - Preferred:

I would like to create a separate subnet consisting of all the devices connected to the R6230 (both by Ethernet and wirelessly). The R6230 would distribute DHCP to all these devices. The devices on this subnet will not see any devices on the main network and vice versa. 

 

Option 2 - Compromise:

The R6230 would be configured in the same manner as the current Apple AIrports.  

The R6230 would distribute via DHCP a specific subset of the main network IP addresses to all connected devices (both by Ethernet and wirelessly). The devices on this subnet will see all devices on the main network and vice versa. 

 

I have been looking at the online user guide. It is not clear to me how to accomplish either of these options. If Option 1 can be done, I won't need the instructions for Option 2.

 

Thank you in advance.

   That's one (private-address?) subnet, or what?  Actual numbers might
help my feeble, concrete-bound brain.

   How, exactly, is that arranged?  If they're acting as DHCP servers,
then I'd infer that they're not configured as wireless access points, so
they must be configured as routers?  How, exactly?

   Ok.

   That's an address in your "Large Ethernet Backbone" subnet?

   Without knowing who has which addresses in this scheme, I don't know
who'd need an explicit route to find whom.  Typically, if you just tack
a new router (with a new LAN subnet) onto an existing network, then
devices on the existing network won't know how to reach devices on the
new-router LAN subnet.  But, devices on the new-router LAN will send any
foreign-looking message out to the existing network, and NAT could allow
that to work.

   Have you tried anything simple, like connecting the R6230 and seeing
what happens?

   Which is how, exactly?
