Summary page for customers/guests

[polhallen]

Hi all,
I'd like create a "summary page" (no popup because all browsers blocks it) with useful information about own connection:

• ip;
• remaining time;
• a button to DISCONNECT from network;
• and any useful information is possible adding;

anyone can help me or give me a clue?

thanks for help!

Maybe can useful for who use captive portal for guests or work's purpose.

cheers!

PS: why in pfsense there isn't this feature as default?
