Captive Portal

Dear All,

I would like to pop up a page for captive portal when users are in idle mode. For example the idle setting in the m0n0 to 10 mins. For example, users are idles for 5 mins, there should be a messagebox showing that they will be terminated from m0n0 soon and there is a button for them to resume as well.

Could anyone advise how we can achieve this?


Regards,

LG
