Captive Portal zone from restored config not named, status page 2.1 blank

[islandwifibill]

Hi all.

ok, after upgrading from 2.0.1 by doing a config backup, then fresh live cd install of 2.1, then restore config, my captive portal status doesn't show the logged in users.  I notice the new "zones" setup, and the 'restored' captive portal instance is there (albeit unnamed).

What do I need to do to 'name' this instance, which I suspect will allow me to see the logged in users under status->captive portal?
