Unidirectional cable modem (modem up, cable down)

NOTE: This type of Internet connection is not an "officially supported configuration" as the settings may vary from ISP to ISP. However, we try to provide access solutions to as many scenarios as possible. Many of our users have had success with the following settings when trying to establish a connection.

In general, the data flow is similar to DirecPC. Outgoing packets flow through your dial-up interface. On the way back they are routed through a cable. In fact, your ISP has to associate your two interfaces together. This looks tricky but it is the only way to establish a successful link. For this reason, we advise thorough evaluation before going ahead with your purchase of WinRoute

1. Go to menu Settings->Interface Table. You will see a RAS line interface (your modem) and two network card interfaces - one linking to the cable modem and one linking to your local network.

2. Click on the network card interface linking to the cable modem and go to "Properties." Check ON for "Perform NAT with IP address of the interface on all communication passing through."

3. Click on RAS interface and go to "Properties." Check ON "Perform NAT with IP address of the interface on all communication passing through". In RAS tab select the connection you will use to connect your ISP, enter your user name and password.

4. Check than NAT is NOT ON for the Interface linking to the internal network (go to the properties of this interface)

5. Check that there is NO gateway set in TCP/IP properties of the internal NIC (go to network settings) and that NIC has assigned a private class IP address (e.g.10.10.1.1).

6. Check that the NIC linking to the Internet was properly assigned with data from your ISP (TCP/IP properties.) Note: In case you have a dynamically assigned IP address leave IP address settings blank.
