Nowifidog only for guest WIFI

Dear all,

I have set-up a guest network on my router following this howto:

https://openwrt.org/docs/guide-user/network/wifi/guestwifi/guest-wlan

additionally to my existing "private" network.

How can I configure nodogsplash to show only on this guest network and not on the private network? I cannot find anything in the documentation.

Thank you,
alex
