Anti - Spoof
The Anti - Spoof protection is to create some firewall rules assigned to the
external interface (WAN) of the firewall that examines the source address
of all packets crossing that interface coming from outside. If the address
belongs to the internal network or the firewall itself, the packet is dropped.
Values
Enable / Disable
Packet Normalization
Packet Normalization is the normalization of packets so there are no
ambiguities in interpretation by the ultimate destination of the packet. The
scrub directive also reassembled fragmented packets, protecting some
operating systems from some forms of attack, and drops TCP packets that
have invalid flag combinations.
Values
