NAT traversal
Gateways support the following mechanisms for NAT traversal.
Off
Static NAT
Dynamic NAT
STUN
Usually, static NAT is used when fixed public IP address is available. It is necessary to
perform port mapping or DMZ function on the router when selecting Dynamic or static
NAT.
For Aeonix
From the
NAT traversal
drop-down list,
select
off
.
Refresh period
The refresh time must be filled in when selecting Dynamic NAT or STUN traversal. Besides,
refresh time interval shall be determined by giving consideration into the NAT refresh time
of the LAN router which the gateway is located. Gateway’s NAT holding function and
STUN function will carry out periodical operations according to this parameter. With
seconds as its unit, default value of 60 sec.
SDP address
This parameter determines the IP address used in transmitted SDP.
NAT IP Address: Apply NAT address into the transmitted SDP;
Local IP Address: Apply the gateway’s IP address into the transmitted SDP.
Note: The parameter should come into effect only when the gateway successfully obtained a
NAT address.
NAT IP address
This parameter must be filled when using static NAT traversal, where IAD works under
LAN and the WAN address is fixed. The WAN address should be filled in this field, which
will be used in SDP. This parameter can be set in IP address format or hostname format
(note: DNS service should be activated when hostname format is used). There is no default
value for this field.
