Gateway Computers

3 Network Design Before purchasing equipment or deciding on a hardware platform, you should have a clear idea of the nature of your communications problem. Most likely, you are reading this book because you need to connect computer networks together in order to share resources and ultimately reach the larger global Internet. The network design you choose to implement should fit the communications problem you are trying to solve. Do you need to connect a remote site to an Internet…

your PC. If you need instructions as to how to do this, please refer to "Appendix B: Configuring the PC". 2) Configure the network parameters. The IP address is 192.168.1.xxx ("xxx" is any number from 2 to 254), Subnet Mask is 255.255.255.0, and Gateway is 192.168.1.1 (The Router's default IP address). 2. Obtain an IP address automatically 1) Set up the TCP/IP Protocol in "Obtain an IP address automatically" mode on your PC. If you need instructions as to how to do this, please refer to…

you the current WAN IP. Figure 2.3  Obtain the WAN IP address from the router You can find the WAN IP in your router. Normally, it is in system status. Take the WRT54G router of LINKSYS for example, 1) Obtain the IP address of the router(LAN gateway address),user name and password for login the router from the network administrator, 2) Enter the LAN IP address of the router (LINKSYS WRT54G, such as: default LAN IP is 192.168.1.1) in the address bar of the IE to login the router; Open…

protocolo para comunicação. Desta forma, faz-se necessário o uso de um “tradutor” para estabelecer a conexão. Os gateways, entre outras funções, desempenham o papel de estabelecimento de comunicação em uma rede com heterogenia de protocolos. Um gateway pode ser um computador pessoal com mais de uma placa de rede ou então um dispositivo dedicado. Quando se configura uma rede que irá usar um gateway para estabelecer a comunicação, é necessário configurar o endereço deste equipamento para…

Palavras-Chave: Convergência, VoIP, Qualidade de Serviço, PABX IP ABSTRACT IP Voice technology is becoming an important research area the measure in that it increases the number of network computer interlinked, fact impelled by the growth accelerated the use of the internet and of the evolution of the communication means along the years, rationalizing costs and investments. This work presents important studies of the…

acontecer em um único dispositivo. Isto vai tornar mais fácil a implantação e manutenção da rede. Este dispositivo é um gateway da camada dois, isto é, uma ponte (bridge), sem endereço IP. Ele não faz roteamento nem decrementa o TTL(Time to live) dos pacotes. Com isso, os invasores não conseguem perceber que o tráfego está sendo analisado. A segunda vantagem é que, como um gateway, todo o tráfego de entrada e saída passa por ele. A figura 2 representa um Honeynet de Segunda…
