(1) A node on a network that serves as an entrance to another network. In enterprises, the gateway is the computer that routes the traffic from a workstation to the outside network that is serving the Web pages. In homes, the gateway is the ISP that connects the user to the internet. In enterprises, the gateway node often acts as a proxy server and a firewall. The gateway is also associated with both a router, which use headers and forwarding tables to determine where packets are sent, and a switch, which provides the actual path for the packet in and out of the gateway. (2) A computer system located on earth that switches data signals and voice signals between satellites and terrestrial networks. (3) An earlier term for router, though now obsolete in this sense as router is commonly used. router (n.) A device that forwards data packets along networks. A router is connected to at least two networks, commonly two LANs or WANs or a LAN and its ISP's network. Routers are located at gateways, the places where two or more networks connect. Routers use headers and forwarding tables to determine the best path for forwarding the packets, and they use protocols such as ICMP to communicate with each other and configure the best route between any two hosts. Very little filtering of data is done through routers. jadi router itu selalu gateway, tetapi gateway belum tentu router (hehehehe mudeng deh..) karena fungsi router hanyalah memforward paket2 data saja, sedangkan gateway bisa berfungsi sebagai firewall atau proxy. Dengan iptables kita bisa memfilter data yang masuk keluar tapi tidak bisa meroutingkan. Untuk routing bisa menggunakan iproute2, bahkan NAT atau DNAT pun bisa dengan iproute2. lordsanjay -- Unsubscribe: kirim email kosong ke [EMAIL PROTECTED] Arsip dan info di http://linux.or.id/milis.php FAQ milis http://linux.or.id/faq.php
