The RG231 provides four 10BASE-T/100BASE-TX RJ-45 ports. These LAN
ports are standard RJ-45 Ethernet network ports that connect directly to
PCs. They can also be connected to an Ethernet switch or hub to support
more users.
All ports support automatic MDI/MDI-X operation, so you can use straightthrough cables for all network connections to PCs or servers, or to other
switches or hubs. Each of these ports support auto-negotiation, so the
optimum transmission mode (half or full duplex), and data rate (10 or
100 Mbps) is selected automatically.
Each RJ-45 port includes a built-in LED indicator. This LED indicator is
described in the following table.
Table 5: LAN Port Status LEDs

The information in this chapter covers the configuration options for the
RG231’s Internet gateway functions.
The RG231 provides comprehensive firewall features and NAT isolation for
Internet traffic passing from the WiMAX service provider to the local
network connected to the LAN ports. The DHCP server feature can assign
IP addresses for up to 32 local network PCs and wireless clients.
The Advanced Setup menu includes the following items for Internet
gateway configuration.

Network Address Translation (NAT) is a standard method of mapping
multiple "internal" IP addresses to one "external" IP address on devices at
the edge of a network. For the RG231, the internal (local) IP addresses are
the IP addresses assigned to local PCs by the DHCP server, and the
external IP address is the IP address assigned to the WiMAX interface.
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

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.
