Configuration Guidelines for NAT

MAXCS ACM 6.7 Administration Manual

A switch is required; VoIP quality can be adversely affected if a hub is used.
Configuration Guidelines for NAT
Note:
This section only applies to AltiGen IP phones or IPTalk integrated with
MaxCommunicator or MaxAgent.
The section discusses the configuration guidelines when MAXCS is behind NAT (Network
Address Translation) and communication to AltiGen IP phones, IPTalk, or another MAXCS
is over WAN. AltiGen SIP phones support NAT traversal, which does not require special
settings on the NAT router at the remote site.
Due to H.323/SIP protocol, which puts the IP address information in the TCP/IP payload,
the NAT router requires some H.323 protocol and SIP protocol implementation to
correctly handle the H.323/SIP traffic and translate the private IP address into a public
IP address. Not all NAT routers have this kind of implementation. If the NAT router does
not support H.323/SIP,
you need to check
Enable SIP NAT support
and
Enable H323
NAT support
in Enterprise Manager,
IP Networks
tab.
The following sections illustrate a private network configuration and a VPN configuration.
For information on setting up VoIP traffic forwarding for NAT and configuring MAXCS
behind NAT, see “Configuring MAXCS Behind NAT” on page 327.
Private Network Configuration Example
(MAXCS with private IP address and behind NAT)
Only the private IP address is used in a private network—the public router will not route
the packet that has a private IP address as its destination. (All IP addresses beginning
with 192.168.x.x, 10.x.x.x, or 172.16.x.x to 172.32.x.x are private IP addresses.)
