Enable AltiServ NAT
Support for H.323 In the case where ACM is behind NAT, this NAT
support feature allows ACM to make H.323 IP calls
through NAT, even when the NAT router does not
support H.323. When this option is selected, the
following check boxes are enabled in the
NAT
Support field:
• Public Address in NAT Server - enter the public
IP address of NAT router.
• Use Private Address in Private Network - by
default, this check box is enabled. In the Private
Network field, enter the Subnet Address and the
Subnet Mask of the private IP address of the
H.323 endpoint. ACM does not perform NAT
address translation in H.323 packets for the IP or
any other H.323 devices which sit in this
specified private network.
Note: After setting up the H.323 traffic forwarding
for NAT, if both incoming and outgoing
connections work without enabling this
feature, this means the NAT router supports
H.323. In this case, this feature does not need
to be turned on.
For more information on configuring NAT, refer to
“Configuration Guidelines for NAT” on page 9-12.
