Firewall IP Option
Configure IP option settings. IPv4 options are added to the basic IPv4 header to provide additional features beyond those that are supported by the standard IPv4 packet's header. The standard 20-byte IPv4 header can be expanded to have up to 40 bytes of options. IPv6 options have no fixed size, but are otherwise similar to IPv4 options and provide for many of the same features.
Note:
This web page is controlled by the Security Profiles field in the Personal Firewall Basic Configuration page. If a fixed profile (without the word 'Custom' in the name) is selected, this web page is read-only and no configuration change is allowed. The Edit column, "Apply", "Add Rule" and "Purge Table" buttons are removed. If a custom profile is selected, configuration change is allowed on this web page.
