Network requirements

authentication/authorization server.
Detailed requirements are as follows:
The host is assigned with a public network IP address either manually or through DHCP. Before
•
passing portal authentication, the host can access only the portal server. After passing portal
authentication, the host can access the Internet.
The access device (Router) can detect whether the portal server is reachable and send trap
•
messages upon state changes. When the portal server is unreachable due to, for example, a
connection failure, network device failure, or portal server failure, the access device can disable
portal authentication, allowing users to access the Internet without authentication.
The access device can synchronize portal user information with the portal server periodically.
