Private and Public Network Configuration (AltiWare with Both
Private and Public IP Addresses)
Figure 8. AltiWare on Multi-Homed Host
In the case of insufficient public IP addresses for local IP phones, IP phones
can be located in a private network. With private IP addresses assigned,
when assigning two IP addresses (one public and one private) to AltiWare,
H.323 NAT is not required in the local network.
Figure 4 shows this network layout, where the AltiWare is installed and
running on a multi-homed host with private IP address 192.168.1.2 and
public IP address 169.254.101.2.
IP Phone 1 uses the private IP address 192.168.1.100 and IP Phone 2 uses
the public IP address 169.254.101.100. There are two remote IP phones. IP
Phone 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 one, IP Phone 4,
with a public IP address 202.101.54.61, connects to the Internet directly.
