25 roaming users needs to connect to the network and access application.
It can be 25 concurrent or max 25 connections. It needs to be secured and authentication through ACS integration.
Will 2811 fullfill the requirement. Do I need any additional License?
Do I need Cisco VPN Client? All users are running Windows7 or XP.
Do I need a Firewall or 2811 can be configured with good security
