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. QUANMA-T (config) # ip local

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 sim

Premise: With the development of the network, network security has become an important topic at present. More and more companies will choose to use the firewall as the company's egress device. Compared with the router, the firewall not only has the forwarding routing function, it can also filter internal and external traffic to further enhance the security of the company's network.

There are many VPN products on the Cisco ASA Web VPN configuration market and their technologies are different. For example, in the traditional IPSec VPN, SSL allows the company to achieve more remote users to access the VPN in different locations, this service enables more network resources to be accessed and has low requirements on client devices, reducing the
