Cable modem (Bi-directional) connection

Cable modem connection requires two Network Card Interfaces (NIC) included in the WinRoute computer. One NIC will link to Internet (cable modem) while another NIC will link to the internal network. For UNI-directional cable modems (modem up, cable down) refer to the next section.

Connection via Cable modem (Bi-directional)

WinRoute Configuration

  1. Go to menu Settings->Interface Table
  2. Choose NIC linking to the Internet, click on Properties and check ON "Perform NAT with IP address of the interface on all communication passing through". When opening the interface table dialog box you will see NAT ON beside this external line.
  3. Check than NAT is NOT ON for the Interface linking to the internal network (go to the properties of this interface in Interface Table)
  4. Check that there is NO gateway set in TCP/IP properties of the internal NIC (go to network settings) and NIC has assigned an internal IP address.
  5. Check that the NIC linking to the Internet was properly assigned with data from your ISP. In case you have a dynamically assigned IP addresses leave the IP address settings blank.

For other network settings refer to appropriate chapters (e.g. checklist, IP configuration etc.)
