4. Does the Linksys WRT1900ACS support SPI firewall?
Yes, this helps protect your local network from Internet threats. This option is enabled by default.
5. Does the Linksys WRT1900ACS offer a Filter IDENT that block specific Internet data types?
Yes, this feature keeps port 113 from being scanned by devices outside of your local network. This
option is enabled by default.
6. What is Demilitarized Zone (DMZ) and what is it used for?
The DMZ feature allows one (1) local user to be exposed to the Internet for use of a special-purpose
service such as Internet gaming and videoconferencing (VC). The DMZ hosting forwards all the ports
at the same time to one (1) computer.
NOTE: Port Forwarding is more secure compared to enabling the DMZ feature because it only opens
the ports you want to open.

The Linksys WRT1900ACS supports DynDNS.org and NO-IP.com providers.
