Experiment Name: Cisco router network address translation (NAT)Experimental purpose: To achieve all intranet IP to use a small number of public IP network connection to the InternetExperiment Introduction:With the help of NAT technology, when the intranet private address sends packets to the router, the private address is converted to a legitimate public IP addre

Here we will mainly introduce the configuration and initial installation of Cisco routers. Describes how to configure Cisco router settings and remote access, this article discusses how to use the DHCP service function of the internal network to allocate address information for users who remotely dial in and how to tro

Cisco router has become a commonly used network device, but we are not very clear about its storage classification. Here we will introduce it in detail. Memory category: 1: RAM: Random Access to memory, equivalent to computer memory 2: ROM: read-only memory. Some microcodes used to start and maintain the router are resident in the ROM. 3: FLASH Memory, equiva

I. Overview: In the actual work can often see a strong SSL VPN can bypass deployment, and support routing mode and NAT mode: Router mode requires intranet to VPN assigned address pool address can be router; NAT mode, VPN Client access intranet host, intranet host sees address as VPN interface address, Therefore, the address intranet of the VPN address pool is not required to be routed. If you want to test
