Firewall 53
3 If required, check the RIP defect check box. This feature stops
unacknowledged packets from accumulating in the input queue.
Stateful Packet Inspection
4 The Stateful Packet Inspection section displays a list of traffic types. If you
leave the check box for a traffic type blank, this traffic type is blocked. If
you check the check box, the Router allows this type of incoming traffic,
but only if the connection was initiated from the local LAN.
For example, if you check only the FTP Service check box, all incoming
traffic is blocked except for FTP connections initiated from the local LAN.
