" Filter IP Source Route Option: Each IP packet can carry an optional field
that specifies the replying address that can be different from the source
address specified in packet’s header. Hackers can use this address field on
disguised packets to invade LAN networks and send LAN networks’ data back
to them.
" Detect Port Scan Attack: Select this option to detect the port scans hackers
use to continuously scan networks on the Internet to detect computers and
vulnerable ports that are opened by those computers.
" Detect Land Attack: Some Systems may shut down when receiving packets
with the same source and destination addresses, the same source port and
destination port, and when SYN on the TCP header is marked.
Enable this function to detect such abnormal packets.
After enabling the needed detect functions, click OK to activate the changes.
