I have the following scenario:
Main Office: SBS2003 Premium DC (ISA 2004 + Exchange 2003 on premises) + 2 Windows 2003 TS with
5 small office connected on VPN (Cisco router <-> Cisco router)
I have to migrate to Windows 2012 R2 DC + Exchange 2013 on premises + 2 Windows 2008 R2 TS (with legacy appplication not compatible with Windows 2012 R2 at the moment) and Cisco ASA 5012X acts as firewall.
Wich is the best VPN solution on the new scenario ?
Cisco router -> Cisco ASA ? or Cisco VPN client on every client on the small office to Cisco ASA ?
Thank everybody would give me a suggestion
