I'm adding WiFi to my Shorewall router.

In "step 1" (earlier thread) I added a wifi adapter, device == wlan0, to zone 
== wifi0.

I assigned a unique segment to its DMZ, 10.128.128.0/24, whereas the rest of my 
LAN is on 10.1.1.0/24.

Using policies I set it up for passthrough access

        net    wifi0   ACCEPT
        wifi0  net     ACCEPT
        all    wifi0   REJECT
        wifi0  all     REJECT 

got DHCP & PING working, and got hostapd running with wlan0.

Now I can log in to the wifi0 zone, get an IP in its segment, and access the 
net -- bypassing the 'net.  Exactly what I wanted.

I learned that hostapd can broadcast multiple SSIDs on a single adapter.

As 'step 2', I want to add a second SSID for login -- but integrated into my 
LAN, *not* isolated from it.

I configured hostapd so that it creates two 'virtual' interfaces,

        wlan0, 10.128.128.0/24
        wlan1, 10.2.2.0/24

I want wlan1 'fully integrated' into my LAN -- subject to same access rules, 
protections etc., while wlan0 still functions exactly as above.

IIUC I can either

(1) put wlan1 on a bridge with my already setup internal ethernet interface
(2) put wlan1 in another DMZ segment, and setup access policies or rules

I understand from docs how I'd do (1).

I want to figure out how to do (2) safely.

If I assign the 2nd interface, wlan1, to a 2nd zone == wifi1, & add policies

        net    wifi0   ACCEPT
        wifi0  net     ACCEPT
        all    wifi0   REJECT
        wifi0  all     REJECT
        $FW    $FW     ACCEPT
        $FW    all+    ACCEPT
+       wifi1  $FW     ACCEPT
+       lan    wifi1   ACCEPT
+       wifi1  lan     ACCEPT

will that provide my wifi1-logged-in users full access to the LAN == lan zone, 
**AND** keep it safely isolated from the 'passthrough' wlan0?

I want to make sure that since 'wlan0' and 'wlan1' are both attached to the 
same PHYSICAL interface -- on the same adapter, coordinated/assigned by hostapd 
-- that I'm not somehow re-opening an insecure 'leak' between wlan0 and my LAN, 
by providing that access to wlan1.
