Router wireless Cisco 878WTestat / functionalBasic Specs Cisco 878W-G-E-K9Type: Wi-Fi ADSL access pointSupport ADSL2+: yesWireless standard: 802.11g The 802.11g specification is a standard for wireless local area networks (WLANs) that offers transmission over relatively short distances at up to 54 megabits per second (Mbps) compared with the 11 Mbps theoretical maximum with the earlier 802.11b standard.Max. speed of the wireless connection: 54 MbpsReception/transmission Cisco 878W-G-E-K9Protection of information: WEP WPA WPA2 802.1xOptions access point/bridge Cisco 878W-G-E-K9Switch: 4xLANRouter Cisco 878W-G-E-K9Router: yesFireWall: A firewall is a network security device that grants or rejects network access to traffic flows between an untrusted zone (e.g. the Internet) and a trusted zone (e.g. a private or corporate network). The firewall acts as the demarcation point or a€ traffic copa€ in the network as all communication should flow through it and it is where traffic is granted or rejected access. Firewalls enforce access controls through a positive control model which states that only traffic defined in the firewall policy is allowed onto the network all other traffic is denied. yesNAT: The use of Network Address Translation (NAT) has been wide spread for a number of years this is because it is able to solve a number of problems with the same relatively simple configuration. At its most basic NAT enables the ability to translate one set of addresses to another. This enables traffic coming from a specific host to appear as though it is coming from another and do it transparently. This article looks at some of the basic concepts that are used when configuring NAT and reviews the configuration steps required to get NAT working. yesDHCP server: Dynamic Host Configuration Protocol (DHCP) is a client/server protocol that automatically provides an Internet Protocol (IP) host with its IP address and other related configuration information such as the subnet mask and default gateway. RFCs 2131 and 2132 define DHCP as an Internet Engineering Task Force (IETF) standard based on Bootstrap Protocol (BOOTP) a protocol with which DHCP shares many implementation details. DHCP allows hosts to obtain necessary TCP/IP configuration information from a DHCP server. yesSupport for Dynamic DNS: yesDynamic routing protocols: RIP v1 RIP v2VPN Cisco 878W-G-E-K9Support for VPN pass through: yesSupport VPN tunnels: VPN supports two types of tunneling - voluntary and compulsory. Both types of tunneling are commonly used. In voluntary tunneling the VPN client manages connection setup. The client first makes a connection to the carrier network provider (an ISP in the case of Internet VPNs). Then the VPN client application creates the tunnel to a VPN server over this live connection. In compulsory tunneling the carrier network provider manages VPN connection setup. When the client first makes an ordinary connection to the carrier the carrier in turn immediately brokers a VPN connection between that client and a VPN server. yesAntenna Cisco 878W-G-E-K9The number of external antennas: 1 x 2.2 dBiExternal antenna type: fixedMonitoring and configuring Cisco 878W-G-E-K9Console port: yesWeb-interface: yesSupports Telnet: Telnet is an application layer protocol used on the Internet or local area networks to provide a bidirectional interactive text-oriented communication facility using a virtual terminal connection. User data is interspersed in-band with Telnet control information in an 8-bit byte oriented data connection over the Transmission Control Protocol (TCP). yesSNMP support: SNMP (Simple Network Management Protocol). SNMP is an a€ agentlessa€ method of monitoring network devices and servers and is often preferable to installing dedicated agents on target machines. Thousands of different network devices and operating systems from different vendors support SNMP for delivering critical information on health and usage metrics service state and more. yesMemory Cisco 878W-G-E-K9RAM: 128 MBThe size of flash memory: 24 MBDetailed Specs Cisco 878W-G-E-K9Power over Ethernet cable (PoE): yesFlash memory: yesDimensions (WxHxD): 260x51x232 mmWeight: 954 g
