Dynamic DNS Stateful Inspection Firewall

Security

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.
