Alti-IP 600H Manual 29
Configuring NAT
NAT (Network Address Translation) is the translation of an IP address
used within one network to a different IP address known within another
network. One network is designated as the inside network, the other is the
outside. The Alti-IP 600H can be enabled to support H.323 behind NAT.
The Alti-IP 600H will be able to work behind a regular NAT router without
any special implementation for H.323.
For more detailed information regarding NAT configuration guidelines and
implementation, refer to the AltiWare OE/ACC or ACM System
Administration Manual.
Note: If more than one Alti-IP 600H phone sits behind NAT, a VPN
tunnel is required to connect between the NAT router and the
corporate router.

4. Press (DOWN key) to select YES.
5. Press the ENTER button.
