One of the most important features for a firewall product is logging events. This blog will show you how to log management and analysis of the ASA, the principle and configuration of ASA transparent mode, and implement URL filtering using the iOS features of the ASA firewall

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.

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.
