the model rp114 router supports the transmission control protocol/internet protocol (tcp/ip) and routing information protocol (rip).

    for further information about tcp/ip, refer to appendix b, “network and routing basics.”

    1?ip address masquerading by dynamic nat+

    the model rp114 router allows 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.

    2?automatic configuration of attached pcs by dhcp

    the model rp114 router dynamically assigns network configuration information, including ip, gateway, and domain name server (dns) addresses, to attached pcs on the lan using the dynamic host configuration protocol (dhcp). this feature greatly simplifies configuration of lan-attached pcs.

    3?dns proxy

    when dhcp is enabled and no dns addresses are specified, the router provides its own address as a dns server to the attached pcs. the router obtains actual dns addresses from the isp during connection setup and forwards dns requests from the lan.

    4?ppp over ethernet (pppoe)

    ppp over ethernet is a protocol for connecting remote hosts to the internet over an always-on connection by simulating a dial-up connection.
