DoS Protection
– 367 –
PARAMETERS
These parameters are displayed:
◆ TCP/UDP Port-Zero Status – Protects against DoS attacks in which
the UDP or TCP source port or destination port is set to zero. This
technique may be used as a form of DoS attack, or it may just indicate
a problem with the source device. Use the no form to restore the
default setting. (Options: Drop, Forward; Default: Drop)
WEB INTERFACE
To set the action to take for packets with Layer 4 port set to zero:
1. Click Traffic, Packet Flow.
2. Set the status to Drop or Forward.
3. Click Apply
