NAT Configurations
Network Address Translation (NAT) allows multiple users at your local site to access the
Internet through a single Public IP Address or multiple Public IP Addresses. NAT provides
Firewall protection from hacker attacks and has the flexibility to allow you to map Private IP
Addresses to Public IP Addresses for Internet applications or sharing your LAN resources such
as H.323 VoIP service, web hosting and FTP service.

Special Applications
Please click on one of NAT features and refer to following sections for further information.
XRT allows one or more Public IP Address(es) to be mapped to a pool
of local Private IP Address(es). This feature is particular useful when
you have multiple public IP addresses and you'd like to divide local
users into different groups.
Virtual server feature is mostly utilized for sharing your LAN
resources toward Internet users. You may assign different LAN side
services (e.g. email, FTP, Web etc.) sharing with WAN users. In the
meantime, Virtual Server feature in XRT allows you to re-direct a
particular service port number (from the Internet/WAN Port) to a
particular LAN IP address and its service port number to prevent port
conflict while the same service is provided from LAN side.
Some applications require multiple connections, such as Internet
games, video conferencing, Internet telephony and others. In this
section you can configure the router to support these types of
applications.
