3 with private IP address 192.168.2.100 connects to the Internet via the
Router 2, which must also support H.323 NAT. Router 2 can also sit behind
a DSL/Cable Modem. Another remote IP phone, IP Phone 4, with public IP
address 202.101.54.61, connects to the Internet directly.
Setup
The following components should be configured:
For the corporate LAN:
• 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.
• IP Phone 1 and IP Phone 2
When configuring the local IP phones, IP Phone 1 and IP Phone 2,
you should set up the AWIP to AltiWare's 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 6-23.
For the Remote IP phone by using NAT:
• IP Phone 3
When configuring remote IP Phone 3, you should set up the AWIP
to AltiWare's 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, which is
192.168.2.100. For information on how to set up the H.323 traffic
forwarding for H.323 NAT, please refer to “Setting up H.323
Traffic Forwarding for H.323 NAT” on page 6-24.
For the Remote IP Phone Directly on Internet:
• IP Phone 4
