In this case, the active FTP server works normally because: ftp review can enable FTP to normally Modify FTP application layer data when traversing PAT), and enable FTP to actively initiate packets from Outside to Inside in active mode to pass the firewall smoothly.

ASA/PIX: Load balancing between two ISP-options
VERSION 7
Is it possible to load balance between two ISP links?
Does the ASA support PBR (Policy Based Routing )?
Does the ASA support secondary IP address on interfaces?
What other options do we have?
SLA RouteTracking
PBR on the router outside the firewall

The following describes the experiment procedure. You only need to disable the routing function on SW1 and SW2. The following is an operation on the ASA firewall to start the startup-config configuration file of ASA.Configure the IP address of the ASA firewall, set the corresponding region, and perform a NAT address translation
Hello everyone!The Global. asa file is an optional file in which you can define event scripts and use Session and Application objects. The contents of the Global. asa file cannot be displayed to users, but the information stored by the Global. asa file can be applied to the entire application. This file must be named Global.
