Web and MAC Authentication
Configuring Web Authentication
• You can block only incoming traffic on a port before authentication
occurs. Outgoing traffic with unknown destination addresses is
flooded on unauthenticated ports configured for web authentication.
For example, Wake-on-LAN traffic is transmitted on a web-authenti-
cated egress port that has not yet transitioned to the authenticated
state;
10. Test both authorized and unauthorized access to your system to ensure
that Web Authentication works properly on the ports you have configured
for port-access using Web Authentication.
Note Client web browsers may not use a proxy server to access the network.
