xport + connecting 2 networks

Hi everybody,

I am a student and have a question about xort.
There are 4 radio transceivers on top of an apartment. Each of them is connected to a hub with a xport, zone 1. az illustrated in below figure.

In addition, there are 4 radios, on top of the other apartment that connected to each other via another hub (zone 2).
Zone 1 and zone 2 can communicate to each other via a wireless connection.

How does the manager send a packet to a radio of zone 2(e.g. the sixth radio)?
Note that, I can't use router to connect these zones.

The xport of radio 4 shall accept all incoming packets (regardless the destination IP address of packet) and send them to the serial port, then I configure the radio 4 to send packets to zone2 via wireless connection ,other than packet with destination IP address 4.

Is it possible to configure xport to do that work?
