Core Settings

Figure 33: Core Networking Settings

This menu allows you to configure core networking settings.

The IPV6 Support field determines where IPV6 interfaces are created and supported at boot time. Set this option to yes if you need these interfaces. Disabling these interfaces removes them from interface displays and OSPF/RIP. A change will take effect at the next boot.

The Antispoofing field corresponds to the kernel rp_filter setting. Setting Antispoofing to “yes” will cause the kernel to reject incoming packets if their source address doesn't match the network interface that they're arriving on, which helps to prevent IP spoofing. If you modify this parameter, the setting be applied to all active interfaces, change the default setting for new interfaces and those created at bootup.

The Ignore All ICMP ECHO field corresponds to the kernel icmp_echo_ignore_all setting. Setting Ignore All ICMP ECHO to “yes” will cause the kernel to reject incoming ICMP ECHO request packets.

The Ignore ICMP Broadcasts field corresponds to the kernel

icmp_echo_ignore_broadcasts setting. Setting Ignore ICMP Broadcasts to “yes” will cause the kernel to reject incoming ICMP ECHO request packets if their destination address is a broadcast address.

The Syncookie Protection field corresponds to the kernel tcp_syncookie setting. Setting Syncookie Protection to “yes” will cause the kernel to protect against SYN flood attacks.
