Altigen AltiWare OE/ACC Version 5.0A Administration Manual page 199

The AltiWare and AltiGatekeeper are installed and running at the
same host with public IP address 16.254.101.2. When installing
AltiGatekeeper, configure as follows:
For Public Address: Redirect Address: 169.254.101.2
Enable Private Access: Disabled
For Private Address: N/A
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 GKIP or GWIP based on the gatekeeper/
gateway mode. In this case, the GKIP and GWIP are the same,
AltiGatekeeper's/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 page
6-27.
For the Remote IP phone by using NAT:
• IP Phone 3
When configuring remote IP Phone 3, 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
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 NAT router with the remote IP phone connected. You
need to set up the H.323FWIP for this 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
page 6-28.
