Stateful Inspection
Stateful inspection is a security feature that prevents unsolicited inbound access when NAT is disabled. You 
can configure UDP and TCP “no-activity” periods that will also apply to NAT time-outs if stateful inspection is 
enabled on the inter face. Stateful Inspection parameters are active on a WAN inter face only if enabled on your 
Gateway. Stateful inspection can be enabled on a profile whether NAT is enabled or not.
UDP no-activity time-out: The time in seconds after which a UDP session will be terminated, if there is no 
traffic on the session.
TCP no-activity time-out: The time in seconds after which an TCP session will be terminated, if there is no 
traffic on the session.
Exposed Addresses: The hosts specified in Exposed addresses will be allowed to receive inbound traffic 
even if there is no corresponding outbound traffic. This is active only if NAT is disabled on an WAN 
inter face.
