Dynamix IAD -162 Gateway
3.1 Behind IP-Sharing
3.1.1 IP Sharing Configuration
3.1.1.1 One Dynamix IAD -162 Gateway behind IAD
This application is only for the user who is using the IP Sharing device. It is said
Gateway is connected behind IP Sharing. The IP Sharing Device must support the
DMZ or Virtual server functions such as ADSL network.
Step 1.
The WAN IP Address obtained from ADSL has two kinds of methods. One is
fixed IP Address, while user applies for one or more fixed IP Addresses.
Another is dynamic IP Address while user applies for dial-up connection way.
Only when the IP address is fixed user can put IAD behind NAT device.
Step 2.
The LAN IP Address of User’s PC can be set as DHCP client in order to gain
a valid one.
Step 3.
One can also assign a fixed IP address, which belongs to the same network
segment as the LAN interface of IP Sharing device.
Step 4.
IAD Gateway must enable the IP Sharing function for the fixed / dynamic
WAN IP Address.
Note:
With Dynamic WAN IP Address, a valid Proxy for Dynamix IAD -162 Gateway
to get register on is a must. In other word, it is not workable in Peer-to-
Peer mode while dynamic WAN IP Address.
Step 5.
IP Sharing device must have a function to do IP/Port mapping. Some is
named as DMZ, some is named as virtual server. The VoIP messages from
WAN have to completely pass forward to the LAN. It mean that if the
Dynamix IAD -162 Gateway is assigned a virtual fixed IP Address such
as 192.168.1.5, IP Sharing device must forward the VoIP message to
192.168.1.5.
