• Max. TCP Sequence Number Difference: 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.
• Enable default mapping to router: This is disabled by default. Toggling this option to Yes will allow the
router to respond to traffic received on this interface, for example, ICMP Echo requests.
