Acess Point

After a guest agrees to the acceptable use

policy, fills in the form, and submits the

registration, the SmartPath AP moves the

client’s MAC address from a quarantined list

to a registered list.

The SmartPath AP then applies the

appropriate user profile to the registered user

and forwards all types of traffic to the rest of

the network, as permitted by firewall policies

assigned to that user profile.
