Action

To edit what action the ZyWALL takes when a packet matches a signature, 
select the signature and use the Action icon.

original setting: Select this action to return each signature in a service 
group to its previously saved configuration.

none: Select this action on an individual signature or a complete service 
group to have the ZyWALL take no action when a packet matches a rule.

drop: Select this action on an individual signature or a complete service 
group to have the ZyWALL silently drop a packet that matches a rule. 
Neither sender nor receiver are notified.

reject-sender: Select this action on an individual signature or a 
complete service group to have the ZyWALL send a reset to the sender 
when a packet matches the signature. If it is a TCP attack packet, the 
ZyWALL will send a packet with a ‘RST’ flag. If it is an ICMP or UDP attack 
packet, the ZyWALL will send an ICMP unreachable packet.

reject-receiver: Select this action on an individual signature or a 
complete service group to have the ZyWALL send a reset to the receiver 
when a packet matches the rule. If it is a TCP attack packet, the ZyWALL 
will send a packet with an a ‘RST’ flag. If it is an ICMP or UDP attack 
packet, the ZyWALL will do nothing.

reject-both: Select this action on an individual signature or a complete 
service group to have the ZyWALL send a reset to both the sender and 
receiver when a packet matches the rule. If it is a TCP attack packet, the 
ZyWALL will send a packet with a ‘RST’ flag to the receiver and sender. If 
it is an ICMP or UDP attack packet, the ZyWALL will send an ICMP 
unreachable packet.
