Allowing one device to bypass portal whenever another is authenticated

[lennykinn1928]

I have a household with 5 kids and they are so horrible at doing there chores that I have created a captive portal with a voucher system.  What I would really like to do is whenever my oldest uses his phone to type in a voucher he is given, I would like it to allow all his devices through without having to go through the portal with each device. So somehow I would have to have a script or something adding the other devices when he authenticates and also removing them when it expires?  Any Ideas?  Thanks

It depends on the Switch or Access Point you have in your LAN

if you have an Access Point that can do Multiple SSID's , VLAN's and Routing Capability then its possible
