Protect against port scan: Blocks for one day any devices characterized as performing a port-scan on the WAN interface. Drop packets with unknown ether types: Ethertypes of 0800, 0806, 8035, 8100, 86DD, 8863, 8864, and 888E are accepted inbound on the WAN interface. Others will be dropped. Drop packets with invalid tcp flags: A list of invalid types is checked and if packet matches, it is dropped. Drop incoming ICMP Echo requests: If enabled, all echo requests coming from the Internet will be dropped. Flood Limit: This feature allows for control of the acceptance of bursting new traffic. When you enable packet flood detection, you can adjust the "Flood Limit" and "Flood Burst Limit". When these limits are reached, the packets will be dropped. Flood rate limit: Limit in packets per second. If a packet flood exceeds this rate, it will be dropped. Flood burst limit: The maximum number of packets in a burst. If a packet flood exceeds this limit, packets will be dropped. Flood limit ICMP enable: Allows you to include or exclude ICMP traffic from flood-limiting. Flood limit UDP enable: Allows you to include or exclude UDP traffic from flood-limiting. Flood limit TCP enable: Allows you to include or exclude TCP traffic from flood-limiting. Flood limit TCP SYN-cookie: Allows you to protect from TCP floods using the technique of TCP SYN Cookies. Neighbor Discovery Attack protection: Limits downstream traffic from an upstream device that sends large amounts of traffic but receives no replies. ESP Header Forwarding: When enabled, this feature allows forwarding of packets from 6rd tunnel endpoints, to and from legitimate node addresses, with an upper layer protocol of type Encapsulating Security Payload (ESP) in their outer IP extension header chain. Authentication Header Forwarding: When enabled, this feature allows forwarding of packets from 6rd tunnel endpoints, to and from legitimate node addresses, with destination extension headers of type Authenticated Header (AH) in their outer IP extension header chain. Reflexive ACL: When IPv6 is enabled, you can enable Reflexive Access Control Lists to deny inbound IPv6 traffic unless this traffic results from returning outgoing packets (except as configured through firewall rules). © 2013 Motorola Mobility Intellectual Property.
