A
Network Address Translation
Network Address Translation (NAT) lets home office or small
network environments use internal IP addresses for the devices
within the network, while using one external IP address to
communicate with the outside world (Wide Area Network). However,
many Small Office Home Office (SOHO) routers provide NAT
services that are not fully H.323 compliant.
Therefore, this solution is provided to enable the user make calls
outside
the internal network.
Note
At this time, it is not possible to make video conferences
calls within the internal network when using the NAT setting.
To make video conferencing calls within the network when using this
solution, simply de-select the
System is behind a NAT
option and
make the call. Re-select the
System is behind a NAT
option to
re-activate this feature and make external calls.
Before You Start Configuring NAT
1.
Determine your NAT’s external (WAN) IP address. This is the
address assigned to your NAT’s external interface (connected to
the Internet).
2.
Determine the IP address of your ViewStation. This can be
found on the
System Information
screen.
Setting up NAT
1.
Go to the
Quality of Service and Firewalls
screen (
System
Info > Admin Setup > LAN/H.323 > H.323 > QoS
).
2.
Select
Use Fixed Ports
.
3.
Select
System is behind a NAT.
