Local Server Setup The Broadband ADSL/Cable SOHO router offers support for hosting servers on your private network that can be accessed from the public Internet. While the addresses on the Broadband ADSL/Cable SOHO router are not directly accessible by a computer on the Internet, yet the Broadband ADSL/Cable SOHO router allows for selective access by mapping incoming access requests for a particular service to a designated host that can really process requests for a specific Internet service on your LAN. For example, in your network there is a host providing the FTP service. The IP address of the FTP server is 192.168.10.250 and the TCP port number for the FTP service is 20. You can map the one of the Broadband ADSL/Cable SOHO router s TCP communication port numbers, such as 20, to the FTP server. The setup procedures are as follows : 1. Click Advanced Setup in the left-column. It then appears the sub-menus. 2. Click Local Server. 3. In the Local Server Mapping field, click Add TCP Entry or Add UDP Entry button. 4. In the External Port No., enter 20. 52
5. In the Physical IP Address option, type the 192.168.10.250. 6. In the Internal Port Number option, type the port number that is used by FTP service (20). 7. Click Save button. 8. Now the setting will be displayed in Local Server List mapping table. 9. Click Save button. 10. Click Save and Restart in the left-hand column for new settings to take effect. 11. Done. Note: Internet computers trying to access your local server(s) listed in the Local Server List must use the IP addresses of the Modem 1 and Modem 2 ports (obtained automatically from your ISP(s) when connected to the ISP). 53
Routing Table The device can allows users to define the internal routing table to best integrate this router into the current IP (sub) network. Note: Defining a new routing requires more advanced TCP/IP knowledge. Any wrong routing information may make the whole IP network unreachable, till it is corrected again.
