. Setting up TelnetTelnet has a version of the change. Before the PIX OS 5.0 (the version number of the PIX OS), the PIX can only be accessed via Telnet from hosts on the internal network. In PIX OS 5.0 and later versions, Telnet to PIX Access can be enabled on all interfaces. When you want to telnet to the PIX firewall from the external interface, the Telnet traffic needs to be protected with IPSec, which means that the user must configure the PIX to

Enter the pix 515e using the superuser (enable), the silent password is empty, change the password with the passwd command. Firewall ConfigurationThe following describes the basic configurations used in general.1. Create a user and change the passwordIt is basically the same as a cisco ios router.2. Activate the Ethernet portYou must use enable to enter, and then enter configure mode.Pix515e> enablePassword

With the development of China's routing industry, its application is also more extensive, especially the application of routers and firewalls. Here we mainly explain the security configuration of NetEye firewall and Cisco router. Firewall has become a key part of enterprise network construction. However, many users thi

Abstract: This article describes the first time that the author personally contacts the Cisco PIX Firewall and summarizes ten basic configurations of the firewall. A hardware firewall is a wall between networks to prevent illegal intrusion and filter information. In terms of structure, it is simply a PC-type computer

With the development of the international interconnection Network, some enterprises have established their own intranet and connected with the Internet through a dedicated line. In order to ensure the security of intranet, it is necessary to use dedicated firewall computer to prevent illegal intrusion. The router firewall can only be used as a filter and cannot hide the internal network structure from the i

This article mainly introduces the firewall security configuration for CISCO router IOS, and describes the NAT conversion function. I believe you have read this article to understand CISCO router IOS. Network security technologies include authentication and authorization, data encryption, access control, and security a

First, the introduction The application of hardware firewall, is now more and more, the product is also very rich. Most of the domestic firewall with Chinese instructions and some corresponding configuration examples, but the foreign products are almost no Chinese instructions. Second, physical connection Pix515 appear

Because the network firewall disables all traffic by default, normal network traffic can only be achieved if it is properly configured. 1. Enter the global configuration mode ciscoasa# Configure terminal 2. Select the network interface that you want to use as the external interface of network firewall Ciscoasa (config) # interface Interface-id 3. Specify I

Cisco single-ARM routing configuration One-arm routing, which is to set up multiple logical subinterfaces on the router, one VLAN for each sub-interface. The data on each sub-interface is passed on the physical link to be labeled encapsulated. Cisco devices support ISL and 802.1q (dot1q) protocols. Huawei only supports 802.1q. The difference between dot1q and IS
