Altigen AltiWare OE/ACC Version 5.0 Administration Manual page 203

Router 1 is a NAT router. The local IP phones, IP Phone 1 and IP Phone 2,
use the private IP addresses 192.168.1.100 and 192.168.1.101,
respectively. There are two remote IP phones: IP Phone 3 with a private IP
address 192.168.2.100 connects to the Internet via Router 2, which must
also support NAT. Router 2 can also sit behind a DSL/Cable Modem.
Another remote IP phone, IP Phone 4, with a public IP address
202.101.54.61, connects to the Internet directly.
Setup
For the Corporate LAN:
• AltiWare and AltiGatekeeper
AltiWare and AltiGatekeeper are installed and running at the same
host with a private IP address 192.168.1.2. When installing the
AltiGatekeeper, configure as follows:
For Public Address: Redirect Address: 469.254.56.169
Enable Private Address: Enabled
For Private Address:
— Redirect Address: 192.168.1.2
— Subnet Address: 192.168.1.0
— Subnet Mask: 255.255.255.0
The public IP address of Router 2 should be configured as the IP
address of this IP extension in AltiWare. If it is changed
dynamically, then assign dynamic IP address configuration for that
extension.
• IP Phone 1 and IP Phone 2
When configuring local IP Phone 1 and IP Phone 2, you should set
up the GKIP or GWIP based on the gatekeeper/gateway mode. In
this case, AltiGatekeeper's/AltiWare's IP address are the same,
which is 192.168.1.2.
• Router 1
Router 1 is also a NAT. You need to set up the H323FWIP for this
NAT to the private IP address of AltiWare 192.168.1.2. For
information on how to set up the H.323 traffic forwarding for H.323
NAT, please refer to page 6-28.
