I desire to block video streaming on my network. youtube et al pending the time i have approval for a welb filtering solution


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!

Block websites on cisco asa 5510.


All websites or specific ones?

If you want to block all web traffic, a straightforward rule preventing HTTP traffic (TCP port 80) as well as HTTPS (port 443) will block any and all web access.

If you just want to block specific sites, I'd recommend an access control list (ACL) configured to deny traffic to those specific site's IP addresses.

Hello all can you please help me on how to restore the configuration of my ASA 5520? thanx


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

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
