cisco pix firewall

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 audit. The following types of security gateway

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.
