Cisco ASA 5520 Firewall Questions & Answers
I desire to block video
You can not do content filtering with ASA firewalls with IOS. You will need to buy a content filtering solution, or sign up for a inexpensive content filtering with OpenDNS.org. This is a good content filtering basic system with white and black listing capability.
Good luck!

Problem in installing the asdm image ASA 5520 ver 7.1
I had this same issue on my ASA 5520.
1. Copy the config and IOS image to a tftp server.
2. Format flash (disk0)
3. set rommon server, ip addy, and file settings.
4. tftpdnld
5. Once the system has booted to the image copy the asa image file, asdm image file, and config to flash
6. configure asdm image default location and reload
Hello all
If you are going for factory reset use the following commands
asa>enable
asa#write erase
asa#reload
Dont save the configuration when it prompts for it.
if you want to restore the configuration from the backup
1. You need to have a TFTP server
2. Locate the config file on your TFTP server
3. TFTP server should be reachable from ASA
then
asa#copy tftp flash
give the tftp server ip address
give the configuration file name (as exactly on the TFTP server)
reload
