3.1 Behind IP-Sharing
3.1.1 IP Sharing Configuration
3.1.1.1 One Dynamix DW-01Plus/S Gateway
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 Dynamix DW-01Plus/S 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. Dynamix DW-01Plus/S 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 DW-01Plus/S
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 DW-01Plus/S
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.
