For remote users/employees of the company, connectivity with security is required to access resources and information of the office. Using Cisco AnyConnect and Cisco FTD we can achieve the same. We will configure RA VPN (Remote access VPN) in Cisco FTD and install Cisco AnyConnect software in the client system to achieve the requirement.

Preresiquites
– Import certificate for server authentication.
– Configure LDAP or RADIUS server for user authentication.
– Configure IP address is poor for remote users.
– Upload AnyConnect software.
