the fwg114p wireless firewall/print server 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, routing, and firewall basics.”

    1 the ability to enable or disable ip address sharing by nat. the fwg114p 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, known as nat, allows the use of an inexpensive single-user isp account. this feature can also be turned off completely for using the fwg114p in settings where you want to manage the ip address scheme of your organization.

    2 automatic configuration of attached pcs by dhcp: the fwg114p wireless firewall/print server 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 pcs on your local network.

    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): pppoe is a protocol for connecting remote hosts to the internet over a dsl connection by simulating a dial-up connection. this feature eliminates the need to run a login program such as entersys or winpoet on your computer.

    5 pptp login support for european isps, bigpond login for telstra cable in australia.

    6 classical ip (rfc 1577)

    some internet service providers, in europe for example, use classical ip in their adsl services. in such cases, the firewall is able to use the classical ip address from the isp.
