During installation 2 times "LAN Zone" specification requested

During the installation of Comodo I am asked 2 times for the “Zone” (for LAN)
specification.

I assume I should enter in this step the trusted IP range from my LAN

Much to my surprise there is only ONE IP enterable and not a range.
e.g.
192.168.1.0 - 192.168.0.255

Why ?

What should be the second “Zone” request ? Is this for my (currently disabled) WLAN adapter ?
