How does the SOHO process this information?
Services
A service is the combination of protocol(s) and port numbers associated with a specific application or communication type. To facilitate configuration of your SOHO, WatchGuard lets you select
Network Address Translation (NAT)
All incoming connections through a SOHO automatically use a feature called dynamic network address translation (dynamic NAT). Without dynamic NAT, your trusted, private addresses would not be passed along the Internet to their destination.
Furthermore, the SOHO protects your trusted network by disguising private IP addresses. During an Internet connection, all traffic passed between computers includes their IP address information. However, due to the dynamic NAT feature, applications and servers on the Internet only see the public, external IP address of the SOHO itself and are never privy to the addresses in your trusted network address range when they exchange information with a computer behind your firewall.
Imagine that you install a computer behind the SOHO with the private IP address 192.168.111.12. If this address were broadcast to the Internet, hackers could easily direct an attack on the computer itself. Instead, the SOHO converts the address automatically to the public, external address of the SOHO. When a hacker tries to violate the computer, they are stopped cold at the SOHO, never learning the true address of your computer.
