Packet Tracer 5.2 Experiment (15) network port address translation NAPT configurationFirst, the experimental target Understand the principle and function of NAT network address translation; Master NAPT configuration, realize LAN access to the Internet; Second, the experimental backgroundCorporate office network needs to access the Internet, the company only applied to the ISP a dedicated line, the leased line assigned a public IP add
The newly released packet Tracer 6.2 version number is 6.2.0.0052, divided into student and teacher editions.Fixed some bugs on the previous version, added a new 819 router, a wired sniffer with trunking capabilities, and some new 3g/4g devices.The supported operating systems are WIN7,WIN8 or win8.1. Windows XP has stopped supporting it.Some features are supported for HTTP servers:(1) JavaScript and CSS Sup
Tags: size src zone sha port text topology Cisc-oTwo networks in different regions if you want to communicate, you need to configure routing on the router to implement the packets across the networkRouters can connect to multiple networks, but the router itself does not know about other networks, and we need to manually configure static routes to let routers know about other network information or to config
Network address port Conversion NAPT is a very familiar way of transformation. NAPT is commonly used in access devices, which can hide small and medium-sized networks behind a legitimate IP address.Unlike dynamic address NAT, NAPT maps An internal connection to a separate IP address in the external network, adding a TCP port number selected by the NAT device to the address.This time, let's get to know napt.Configuration ideas1 Configure the router's interface IP address, note the network segment
RIP protocols can be configured in a more convenient way, but the limitations of RIP itself indicate that it is not suitable for medium to large networks. In contrast, OSPF is more complex to configure than RIP, but its functionality and performance are better than RIP.Configuration ideas1 Configure the physical interface address of the router Xia Lian switch and the physical interface address of the router
external IP address to access the Internet, thus saving IP Address resources to the maximum extent. At the same time, all hosts in the network can be hidden to effectively prevent attacks from the Internet. Therefore, port multiplexing is the most widely used network. Iv. Experiment steps Lab Topology 1. R1 is the egress router of the company. It is connected to the ISP router through a serial
Nat[network address translation] In the absence of IP address in the case of a great use, it can not be normal Sisu network of the intranet address into a legitimate external network address on the public network to send and receive data. At the same time address translation function can also be very good to hide and protect the host network.Nat has static NAT (internal address and external address one-to-one) and dynamic NAT (internal address pool and external address Pool A-do)This time we'll
