Defining Your Network
If you need to configure either bandwidth control or NAT support, you have to define
your network first. These are the guidelines:
• You must define your LOCAL network IP address range. When a Pipe is defined as
Local , it tells the system that the configured IP address range is not subject to
bandwidth control. If the AltiGen system and this Local Network are behind the same
NAT router, you need to check the
Private Network check box. This tells the
system that VoIP connection to this address range does not require IP address
translation, which is replacing the system's private IP address with a public address
when sending VoIP packets to outside devices.
• If you have an intranet linking multiple locations, you must enter the IP address
range and define the Pipe as
Intranet . If the AltiGen system and this intranet are
behind the same NAT router, you need to check the Private Network check box.
• If you have VPN service over public WAN, you must enter the VPN IP address range
and define the Pipe as
Public . If the AltiGen system and this VPN IP addresses are
behind the same NAT router, you need to check the Private Network check box.
• All undefined IP addresses fall into the Public Pipe range and are subject to
bandwidth control if the public pipe bandwidth control is enabled.
Note: When AltiServ is behind a NAT router, and you do not check the Private Network
check box, IP phones may not function.
