Autosensing 10/100 Ethernet

The Model RT311 and RT314 routers connect to either a 10 Mbps standard Ethernet network or a
100 Mbps Fast Ethernet network. The local LAN interface is autosensing and is capable of
full-duplex operation.

TCP/IP

The Model RT311 and RT314 routers support the Transmission Control Protocol/Internet Protocol
(TCP/IP) and Routing Information Protocol (RIP).

IP Address Masquerading by Dynamic NAT+

The Model RT311 and RT314 routers allow several networked PCs to share an Internet account
using only a single IP address, which may be statically or dynamically assigned by your Internet
service provider (ISP). This technique, an extension of Network Address Translation (NAT), is
also known as IP address masquerading and allows the use of an inexpensive single-user ISP
account.

Port Forwarding with NAT

Although NAT prevents Internet locations from directly accessing the PCs on the LAN, the router
allows incoming traffic to be forwarded to specific PCs based on the service port number of the
incoming request.
