Description
Use this link to configure TCP/UDP port triggers.
Port triggering is similar to port forwarding, but is
a dynamic function. In other words, the ports are
not held open, and the ports close if no outgoing
data is detected on the selected ports for a period
of 10 minutes
Use this link to configure an IP address that is
visible to the wide area network (WAN). DMZ
hosting is commonly referred to as "exposed host,"
and allows you to specify the "default" recipient of
WAN traffic that Network Address Translation
(NAT) is unable to translate to a known local PC
A DMZ is used by a company that wants to host its
own Internet services without sacrificing
unauthorized access to its private network. DMZ
allows one IP address to be unprotected while
others remain protected. The DMZ is located
between the Internet and an internal network's line
of defense that is a combination of firewalls and
bastion hosts
Typically, the DMZ contains devices accessible to
Internet traffic, such as web (HTTP) servers, FTP
servers, SMTP (e-mail) servers, and domain name
system (DNS) servers
Use this link to create, configure, and control
Virtual Private Network (VPN) protocols and
manage Internet Protocol Security (IPsec) VPN
tunnels.
