Dynamic DNS
Dynamic DNS support allows you to use the free services of www.dyndns.org. Dynamic
DNS automatically directs any public Internet request for your computer's name to your cur-
rent dynamically-assigned IP address. This allows you to get to the IP address assigned to
your Gateway, even though your actual IP address may change as a result of a PPPoE con-
nection to the Internet. See
"Dynamic DNS Settings" on page
210.
Stateful Inspection Firewall
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 interface. Technical details are dis-
cussed in
"Stateful Inspection" on page
262.
