: An enterprise requests a small number of legitimate Internet IP addresses, and many internal network users. The NAT feature enables multiple users to communicate with the external Internet at the same time by using a legitimate IP. third, the hardware configuration and software configuration of the router required for NAT are set: the router that sets the NAT feature must have at least one internal po

Cisco routers use a lot of users, at the same time there will be many problems, the password is forgotten or lost users are very common problems, so I studied the Cisco router password recovery of two methods, here to take out and share with you, hope for everyone useful. When a Cisco

Cisco routers are widely used in network interconnection. Among them, 2500 series routers are widely used in low-end users. So what if you accidentally forget the superuser password of the 2500 series router? Don't be afraid, as long as you can restore as follows:Preparation: a computer running Terminal simulation prog

The company's GPS patrol system needs to go WVPDN to communicate, but before looking for a telecommunications took a CISCO2811, collapsed once, the 2811 is the telecommunications sent, the estimated quality is not how, and then to find the company to buy the same type of equipment, 2811 discontinued, on the Cisco 2911.Yesterday arrived Ah, excited a bit, super terminal connected on, looked at the system configuration, the result of the hand is cheap,

The Cisco router NAC solves the problem. The so-called NAC is an architecture that allows multiple hardware and software components to work together to protect the user's network from adverse client attacks. 1. It is not easy to fully implement NAC, because the entire architecture contains too many different components from other vendors. For example, the architecture contains the NAC Policy Manager and mul

The Internet addresses accessed by computers on the Intranet are mapped to the same legal public IP address. computers on the Intranet can access the Internet by sharing a public IP address. This is the most practical technology. Extended knowledge 1. Enterprises often need to map a port of a specific Intranet computer to a public network. How can I set it on a Cisco

Therefore, in the actual environment, it often corresponds to an IP address. When the SEC is used together, IPSec provides encryption of user data to provide users with better security. The GRE protocol has two main purposes: internal protocol encaps

Essential security commands for CISCO router initialization 1. Security Settings for vro Access Control 1. Strict control over the administrator who can access the vro. Record Filing is required for all maintenance tasks. Www.2cto.com 2. do not access the vro remotely. Even if you need to access the vro remotely, we recommend that you use the access control list and high-intensity password control. 3. Stric

RIP and IGRP are commonly used router configuration protocols. What problems should we pay attention to when configuring RIP and IGRP? What should we do? The following configuration steps provide detailed answers. RIP Protocol RIP (Routing information Protocol) is an Internal Gateway Protocol (IGP) that is widely used earlier and is suitable for small-sized sim

For common users, it is necessary to learn how to back up the Cisco router configuration file to ensure the security of our routers. In recent years, many cities have established urban financial networks. The construction of these networks has promoted the construction of electronic finance in various regions. Vro is a key device of the city financial network and a bridge to the computer network. It can not

Global debugging When configuring a Cisco router, the boundaries between global and interface commands are obvious. In this case, we use "Global" to identify commands that cannot be used for interface debugging or specific transmission media types and Protocol debugging. For example, in vrouters 2500, you can use Debugging commands to analyze the
