Stateful Inspection Parameters are active on a WAN inter face only if you 
enable them on your Gateway.

: To enable stateful inspection on this WAN inter-

face, check the checkbox.

: This is disabled by default. This option will 

allow the router to respond to traffic received on this inter face, for exam-
ple, ICMP Echo requests.

: Enter a value in this field. This 

value represents the maximum sequence number difference allowed 
between subsequent TCP packets. If this number is exceeded, the 
packet is dropped. The acceptable range is 0 – 65535. A value of 0 
(zero) disables this check.

: To enable this option, which causes the router to dis-

card fragmented packets on this inter face, check the checkbox.
