Blocking by IP Addresses

Note: This topic applies to the Edinburgh Release.

IP block rules can be created to block network traffic originating from certain source IP addresses or network addresses. IP block rules are primarily intended to block hostile hosts from the external network, however, it is sometimes useful to use this feature to block internal hosts, for example, if an internal system has been infected by malware.

IP block rules can also operate in an exception mode – allowing traffic from certain source IPs or network addresses to always be allowed.
