The captive portal management (NoCatSplash), was originally called NoCatAuth in older versions.
It provides a simple splash screen web page for clients on your network, which the user clicks through to access the internet.
This is somehow helpful if you want to limit your user access e.g. no automatic connection as user interaction is required.
It is also ideal for public/semi-public networks to remind the end user of legal responsibility linked to usage.
The requirements are very simple and can be ideal for situations where you simply want to give people an idea of whose network they are using.
It is disabled by default.
Note: If Login Time is expired you should re-enter again into the splash page to get a new lease period. Be aware, there is no notice about expired period so, you can loss Internet Access.
