Dear all,

I have recently purchased cisco 881 router and i have been asked to block youtube.

Please do give info if its possible to block http & https traffic on this router.

Thanks in advance.

One way is to configure the 881 as a DNS server, and then configure the domain youtube.com pointing to an invalid IP address (such as 127.0.0.1).

Can you please post the commands to configure 881 as DNS server and point youtube to invalid ip address.

Also i have configured 881 as dhcp router where i have configured dns server(provided by our ISP).  

Do i have to make any changes to dhcp configuration.

Take a look at my config wizard for Cisco 897's.

http://www.ifm.net.nz/cookbooks/890-isr-wizard.html

Copy the config relating to DNS.  Then add something like:

ip dns view block-domains
  domain name-server 127.0.0.1
  dns forwarding source-interface Vlan1

ip dns view-list isp
 view block-domains 1
  restrict name-group 1

ip dns name-list 1 permit .*youtube.com$

Thanks for your effort but i am new to cisco,

can you please let me know how to configure dns and then block youtube.

Also is there any specific protocol which i can use to block any video streaming from cisco router.

Are you able to use the CLI?
