I'm trying to design a centralized VPN architecture with cisco equipments, so every branch office have an dsl or t1 link, in this case i want to connect all the branch offices to the headquarters data center with VPN the questions is:
It is possible to send the branches offices INTERNET traffic trough the vpn ?
If yes, how can i set up this, what the best routing protocol should i use?
What kind of VPN tunnel should i use ?
Should i also put the domain controller for all the branch offices into the headquarters data-center, if yes how can i broadcast the microsoft protocols to join machines into the domain, share printers files and others
The web sense server can be centralized ? if yes how? and which asa appliance must be configured to forward http traffic into the websense (webfilter)
See the design below
A lot of thanks , regards and all what you want
