I. Overview: Static PAT is generally used in external access to the external IP of a port mapping to the internal host service port, so that the external host by accessing the external IP port, it can easily access to the internal host service (need policy release), but see "Cisco ASA 5500 Series Configuration Guide using the CLI, 8.4 and 8.6 documents, the static Pat, like Static Nat, is also bidirectional and confusing as it is intended to be valid

I. Overview: QQ Group has netizens to discuss the policy-map of the ASA firewall of the global and interface order of execution, from the literal meaning can be seen that the two application range is not the same, one is global call, a only in the interface down, Therefore feel that the detailed interface is first called, in order to confirm their own ideas, the decision to build environment verification. Two. Basic ideas: A. Non-conflicting POLICY

This is certainly not the first article on "Quick Guide to building a VPN using Cisco devices, however, we still hope that this guide will become an all-in-one guide for users who use ASA 5505 devices to set up VPN and connect to the Internet. The ASA itself has a setup wizard, but this wizard does not cover all aspects of work required by the user, and some steps are vague, making it difficult for the user

The IPSec VPN realizes the network expansion, the firewall realizes the control and the filtering to the network traffic, therefore has the influence to the IPSec VPN communication. The default ASA maintains a state session only for UDP/TCP traffic, and therefore discards the ESP traffic that is returned. There are two ways to solve the problem One uses ACLs to release ESP traffic. Two applications check IPSec VPN. Experimental topology R1 conf
