When Cisco routers are routed first, when Nat first may be known, inside is routed first, outside is first Nat.Well, for Cisco ASA, it is not the case, most of the first to find the route if the data from inside, in both cases Nat will first route to confirm the interface.

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 configuration and operation support costs.

Lab objectives:
1. Configure static routes to achieve network-wide interconnection.
2. R1 can telnet to R3, R4, and R3. The ACL rules are denied and the R4 cannot telnet to R1 and R3.

The core of the system is a protection mechanism based on adaptive Security Algorithm (ASA), which can provide a stateful, connection-oriented firewall function while intercepting common denial of service (DoS) attacks.

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.

A major part of enterprise security policy is to implement and maintain firewalls, so firewalls play an important role in the implementation of network security. Firewalls are typically located on the edge of the corporate network, which isolates the internal network from the Internet, or with other external networks, and restricts network visits to protect the internal network of the enterprise. The purpose of setting up a firewall is to establish a
