PORT MAPPING Using the NAT Port Mapping feature, remote users can access different servers on your local network using your single public IP address.Remote users accessing services such as web or FTP at your local site thorugh your public IP address, are redirected (mapped) to other local server IP addresses and TCP/UDP port numbers. For example, if you set Type/Public Port to TCP/80 (HTTP or web) and the Private IP/Port to 192.168.7.9/80, then all HTTP requests from outside users forwarded to
CHAPTER 5 | Gateway ConfigurationNAT– 38 –192.168.7.9 on port 80. Therefore, by just using your external IP address provided by your ISP, Internet users can access the services they need at the local addresses to which you redirect them.The more common TCP service port numbers include: HTTP: 80, FTP: 21, Telnet: 23, and SSH: 22.Figure 27: Port MappingThe following parameters are displayed on this page:◆Private IP – The IP address of the server on the local Ethernet network. The specified address must be in the same subnet as the RG231 and its DHCP server address pool. Alternatively, the IP address can be set by selecting a PC from the DHCP client list. (Range: 192.168.1.1 to 192.168.1.254)◆Use Client List – Allows the Private IP to be selected from the DHCP client list.◆Private Port – Specifies the TCP/UDP port number used on the local server for the service. (Range: 1-65535)◆Public Port – Specifies the public TCP/UDP port used for the service on the WAN interface. (Range: 1-65535)◆Services – Specifies port numbers for some of the more common services. (Options: FTP, SSH, Telnet, SMTP, HTTP, HTTPS)◆Comment – A text comment for the forwarding rule.◆Add Rules – Adds the defined rule to the port forwarding table. Use the Delete button next to a rule to remove it from the table.
CHAPTER 5 | Gateway ConfigurationNAT– 39 –DMZ If you have a client PC that cannot run an Internet application properly from behind the NAT firewall, you can open the client up to unrestricted two-way internet access by defining a virtual-DMZ (virtual-demilitarized-zone) host.Figure 28: DMZ SettingsThe following parameters are displayed on this page:◆Enable – Enables the feature. (Default: Disabled)◆DMZ Host – Specifies the IP address of the virtual DMZ host. Alternatively, the host IP can be set by selecting a PC from the DHCP client list. (Range: 192.168.1.1 to 192.168.1.254)◆Use Client List – Allows the host IP to be selected from the DHCP client list.NOTE: Adding a host to the DMZ may expose your local network to a variety of security risks, so only use this option as a last resort.

– 48 –CCABLES AND PINOUTSTWISTED-PAIR CABLE ASSIGNMENTS For 10/100BASE-TX connections, a twisted-pair cable must have two pairs of wires. Each wire pair is identified by two different colors. For example, one wire might be green and the other, green with white stripes. Also, an RJ-45 connector must be attached to both ends of the cable. CAUTION: Each wire pair must be attached to the RJ-45 connectors in a specific orientation. (See “Straight-Through Wiring” on page 49 and “Crossover Wiring” on page 50 for an explanation.)CAUTION: DO NOT plug a phone jack connector into the RJ-45 port. Use only twisted-pair cables with RJ-45 connectors that conform with FCC standards.The following figure illustrates how the pins on the RJ-45 connector are numbered. Be sure to hold the connectors in the same orientation when attaching the wires to the pins.Figure 30: RJ-45 Connector10/100BASE-TX PINASSIGNMENTSUse unshielded twisted-pair (UTP) or shielded twisted-pair (STP) cable for RJ-45 connections: 100-ohm Category 3 or better cable for 10 Mbps connections, or 100-ohm Category 5 or better cable for 100 Mbps connections. Also be sure that the length of any twisted-pair connection does not exceed 100 meters (328 feet).The RJ-45 ports on the unit supports automatic MDI/MDI-X operation, so you can use straight-through or crossover cables for all network connections to PCs, switches, or hubs. In straight-through cable, pins 1, 2, 3, and 6, at one end of the cable, are connected straight through to pins 1, 2, 3, and 6 at the other end of the cable.1881
