TopologyRequirement: You can use the Cisco Firewall ASA to access servers in the Internet and DMZ through the Intranet. servers in DMZ can be published to the network for access by Internet users.I. Use of Cisco simulated FirewallBecause we do not have real devices, we use a virtual system using the Linux kernel to simulate Cisco's

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

Step 1 of Cisco ASA firewall VPN configuration: Create an address pool. To remotely access the client, you need to assign an IP address during logon. Therefore, we also need to create a DHCP address pool for these clients. However, if you have a DHCP server, you can also use a DHCP server.
