Configuration Guidelines for NAT
9-20 AltiContact Manager Administration Manual
• AltiWare
The public IP address of Router 2 should be configured as the IP
address of this IP extension in AltiWare for IP Phone 3. If it is
changed dynamically, then assign dynamic IP address
configuration for that extension.
Important:
If there are two network cards on this multi-homed host, when
configuring the network cards, you should only set the default
gateway for the public interface network card. PLEASE
LEAVE THE DEFAULT GATEWAY FOR PRIVATE
INTERFACE NETWORK CARD EMPTY.
• IP Phone 1
When configuring the local IP phone with private IP address, IP
Phone 1, you should set up the AWIP to AltiWare's private IP
address, which is 192.168.1.2.
• IP Phone 2
When configuring the local IP phone with public IP address, IP
Phone 2, you should set up AWIP to AltiWare's public IP address,
which is 169.254.101.2.
• Router 1
Router 1 is a normal router and the firewall is optional. It is
recommended that the user install a firewall for security reasons.
However, you should configure the firewall to allow the H.323
traffic to reach AltiWare. For firewall considerations, refer to
“Firewall Considerations” on page 9-23.
For the Remote IP Phone Using NAT:
• IP Phone 3
When configuring remote IP phone 3, you should set up the AWIP
to AltiWare's public IP address, which is 169.254.101.2. Note that
only one (1) IP phone can be behind the NAT and connect to the
AltiWare through the H.323 NAT.
• Router 2
Router 2 is a router supporting H.323 NAT with the remote IP
phone connected. You need to set up the H.323FWIP for this H.323
NAT to the private IP address of IP Phone 3 192.168.2.100. For
information on how to set up the H.323 traffic forwarding for H323
NAT, please refer to “Setting up H.323 Traffic Forwarding for
H.323 NAT” on page 9-24.
For the Remote IP Phone Directly on Internet:
