I am not sure if this is the right location to ask these questions, if not please lead me to the right one.
Under the Network Diagram section of the Filtering on Cisco IOS Router document (http://www.cisco.com/application/pdf/paws/110318/ciscoiosurlfiltering.pdf) following line is said.
"In this example, the URL filtering server is located in the inside network".
What I understand from the line above is, I can locate URL filtering server in "outside network" if I want to. Is that correct ?
My real questions are;
Let say that I have two branch office and HQ and they are connected through site-to-site vpn. Is it possible to use URL filter service for both of my branch office, If I locate URL filtering server in HQ. If so, do I need extra license.
Thanks in advance.
