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 host with Flash) and firewall operating systems. Its hardware is similar to the common con
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 intruder's eyes. As long as a computer on the external network is allowed to directly acces

This article mainly describes the connection and conversion of the PIX Firewall during the use of the router. What operations should be taken? The following article will give you a detailed answer.
1. ASA Security Level
By default, the Cisco PIX Firewall applies the security level to each interface. The Safer the network segment,The higher the security level. The
1.ASA Security Level
By default, the Cisco PIX firewall applies security levels to each interface. The more secure the network segment, the higher the full level. Security levels range from 0~100, by default, security level 0 is adapted to E0, and its default name is external (outside), and security level 100 is suitable for E1. And its default name is inside. Use the name if to configure any additional int
The Cisco PIX Firewall installation process is as follows:
1. The PIX will be placed to the rack, after the detection of the power system connected to the power supply, and power on the host.
2. Connect the console port to the PC's serial port and run the HyperTerminal program from the console port into the PIX system;
Configure linux as log service host of PIX, cisco, and huawei-Linux Enterprise Application-Linux server application information. The following is a detailed description. Log host settings

First, the user needs
The user has a Cisco PIX 515E firewall, a netcom's export, and a telecom export. Now to implement the default are to go out of the telecommunications line, and access to Netcom's Web site using Netcom's line out.
Ii. Key points of implementation
1, the first to collect Netcom's IP network segment (this can be searched on the network, or telecom friends want a);
2, in the routing aspect

1.interface command
When configuring the user interface, we often hear about the proper terminology of the interface.
HARDWARE_ID refers to Ethernet 0,e1,e2
Interface_name refers to OUTSIDE,INSIDE,DMZ
Hardware_speed, the production is set to Automatic, but Cisco recommends that we manually configure the speed. About speed and the network transport media you choose.
No shutdown user activates this port on router, in
GetNext request is based on the previous-requested result. Therefore, if two consecutive interfaces have the same IP 127.0.0.1 (table index), GetNext function returns 127.0.0.1, which is correct; however, when SNMP uses the same result (127.0.0.1) to generate the next GetNext request, the request is the same as the previous request, resulting in an infinite loop of the management station.
For example: GetNext (ip.ipaddrtable.ipaddrentry.ipadentaddr.127.0.0.1)

Configuring IPSec Encryption with a shared key in the Cisco PIX Firewall involves four key tasks:
1. Preparing for IPSec
Preparing for IPSec involves determining detailed encryption policies, including determining the host and network we want to protect, and selecting an authentication method to determine detailed information about the IPSec peer, determine the IPSec features we need, and confirm that the e
