2. If using a Static IP (recommended), you will need to input the information manually. In order for DDNS to work,
you must enter valid data, compatible with your network, for all of the network setting fields: IP address,
Subnet Mask, Inbound Port and Host Name.
3. If you are connecting through a router, make sure that you have ‘opened up’ all the required network ports in the port
forwarding section of your router’s setup options. That is, you have directed the router to send any incoming traffic
using those IP ports to the LAN IP address of the eBridge200WPM/WPMH. Useful information about router port
forwarding can be found at www.portforward.com. Different routers may use different terms for port forwarding
function. For instance, D-Link calls it virtual server, Netopia calls it pinholes.
The default port for eBridge200WPM/WPMH is: 80
Note: Port 80 is the default port used for web browsing. Because of this, in order to prevent the average user from
hosting a web server, most ISPs BLOCK traffic using port 80 from reaching the average site. If you only plan to
monitor your eBridge200WPM/WPMH on a LAN, you can use port 80, and don’t have to concern yourself
with routers. However, if you desire remote access to your eBridge200WPM/WPMH, you MUST select functional
ports and set up the port forwarding in your router. Other ports, such as 8080 and 8000, are sometimes blocked by
ISPs as well. What port(s) should be used? There are 65,535 valid IP ports to choose from.
These are broken down into three groups:
• Well Known Ports 0 through 1023.
• Registered Ports 1024 through 49151.
• Dynamic and/or Private Ports 49152 through 65535.
So, rather than encounter a port conflict by choosing a port commonly used for another purpose (like port 25 for SMTP
mail or port 448 for secure sockets), choose an ‘unusual’ port number. For example, add 50,000 to your house number:
50,123 is less likely to lead to a port conflict. For a list of the known and registered ports
