13.5 Port Isolation

When a computer is attacked by malicious programs or has security vulnerability, you can use
port isolation to prevent the virus or attack from spreading through the whole network. Port
isolation stops the communication between the port (connected to the infected/vulnerable
computer) and other port(s).
Once the ZyXEL Device detects that the infected host, C in the following figure, is infected, it
stops this port communicating with it's other ports. The infected host can still access the
Internet to download a patch and remove the virus but cannot communicate with the devices
(A, B and D) connected to other ports (or interfaces). The ZyXEL Device allows traffic
passage between that port and other port(s) automatically once the infected computer is fixed.
