This article describes how to configure the IOS Firewall on a Cisco router. What should we pay attention to when configuring the firewall? The following article provides detailed answers. Pre-configuration on R1, R2, and R3 R1 (config) # int e0/0R1 (config-if) # ip add 172.16.1.1 255.255.255.0R1 (config-if) # no shR1 (config) # ip route 0.0.0.0 0.0.0.0 172.16.1.2 configure Static RoutingR1 (config) # ^

products. In addition, large companies must have their own public IP segments. Based on the above considerations, I decided to use the IP Network Browser tool for the range of 210. 224. *. 1 ~~~ 210. 224. *. 254 IP segment scan to check whether a network device of a Cisco router or vswitch is used. It must be noted that IP Network Browser is a tool in the SolarWinds Network management software set. It can

Cisco routers use many methods in configuration. Using SSH instead of Telnet cisco makes it easier for us to understand the configuration of cisco routers and other knowledge points. Replacing Telnet with cisco router configuration using SSH　The Telnet protocol is a member o

Recently, a friend asked me how to configure static NAT for a Cisco router to allow Internet users to access the Intranet Web and email servers through a Cisco router. Obviously, this function requires NAT between the public IP address and the Intranet IP address. The following are the specific implementation methods.

network management software, such as Cisco CiscoWorks and HP OpenView.4. Cisco configmakerConfigmaker is a free router configuration tool developed by Cisco. Configmaker configures the vro in a graphical manner, and then downloads the configuration to the vro through the network. Configmaker requires the vro to run on

No one liked this, but sooner or later there would be a router crash. All that should be done now is to save the key information in the router memory so as to identify the cause of the router crash and prevent this situation from happening again. To do this, you need to configure the vro to save the core dump information stored on the vro at the time of crash. Ne

Line Protection basically requires that the devices connected to the internet have a ground line, including hosts, workstations, hubs, switches, routers, and MODEM connected To routers. A terminal or PC configured with a Cisco router must also use a valid power supply. Cisco synchronous serial interfaces are commonly used. Different interfaces can be obtained th

This article will discuss the importance of maintaining the password security of a Cisco router, explain the Cisco router mode, and show readers how to configure five passwords for a vro to protect network security. Causes of vro security protection using passwords First, as

At present, China's wireless router industry is developing very rapidly, and its market demand is also very high. Here we mainly introduce Cisco's first dual-band wireless router launched in China, this section describes the features and performance of the vro. In May 19, Cisco launched the Linksys by

As a port device connecting WAN, vrouters have been widely used. Their main function is to connect multiple independent networks or subnets to achieve optimal routing and datagram transmission between the Internet. This article takes the Cisco 2511 vro as an example to introduce four router configuration methods. 1. Use the Cisco

, a PPP frame on its hardware chip can be used to eliminate the overhead of the router's central processor. This feature ensures that the router maintains a high-speed connection over all asynchronous ports at the same time. This is useful in actual management. Especially when several network management experts jointly discuss network faults, the value will be reflected. However, although secondary ports are used as Asynchronous ports, they cannot ach

services such as BIND, IMAP, POP, and sendmail, which are frequently problematic in UNIX systems. Although there are few ways to access a vro, further configuration is required to restrict further access to the vro. Most Cisco routers are still controlled through remote logon and do not adopt any encryption method. Communication Using Remote logon is transmitted in plain text, which easily exposes the logon passw
