Landing Page

This section is used to define how your Hotspot's Landing Page will look like to connecting users.

Note: since Hotspot supports unauthenticated users, they will be using different IPs. Basically IP will incremented based on the prefix provided. So for example if Hotspot network is 192.168.2.0/24 third octet will be incremented. So for IP 192.168.2.254 would increment to 192.168.3.254. If the network is 172.16.0.0/16 it will increment second octet. So for IP 172.16.255.254 it would increment to 172.17.255.254 and so on. After successful authentication, Hotspot will be using network that is set in Hotspot settings > General settings.
