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.

The basics of Cisco PIX Firewalls
Cisco PIX Firewalls can protect various networks. There are pix firewalls for small home networks, as well as PIX firewalls for large parks or corporate networks. In the example of this article,
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 tele
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)
In the SNMP protocol, the MIB table
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

To simplify the PIX firewall configuration, Cisco provides the adaptive Security Device Manager (ASDM). The adaptive Security Device Manager provides a powerful, easy-to-use interface for configuring the selected PIX firewall. (see Cisco's file or the
In order to configure SSH to access the PIX, we need to complete two separate sets of services.
• Configure PIX to accept SSH connections.
• Configure our SSH client to connect to the PIX.

I. Understanding of the PIX FirewallThe pix is a Cisco hardware firewall, which features fast operation and convenient use.There are many models of the PIX, and the number of concurrent connections is an important parameter of the PIX
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. Us
The choice of high-grade complete network security equipment is every successful enterprise essential networking facilities, but in fact there are threats in more networks coming from within the enterprise, so it's not enough to just protect the boundaries of network formation, and building an integrated, multi-level security architecture can provide more thorough and practical protection, To improve the internal security awareness of enterprises is to solve the enterprise network security.

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 I

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.
