Description
Use this page to configure port forwarding for local IP
addresses. Port forwarding allows you to run a server
on the local area network (LAN) by specifying the
mapping of TCP/UDP ports to local PCs or to the IP
address of other devices. This is a static setting that
holds the ports open at all times
Use this page 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 page 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 (email) servers, and domain name
system (DNS) servers
Use this page to create, configure, and control Virtual
Private Network (VPN) protocols and manage Internet
Protocol Security (IPsec) VPN tunnels.
