What should a BIGIP Administrator configure to provide remote access and ensure data privacy?

A security policy defines rules for allowing or denying traffic but does not itself create an encrypted tunnel or provide a remote access mechanism with data privacy.

A packet filter inspects and permits or blocks traffic based on headers but does not encrypt data or provide a dedicated remote access solution.

VPN (Virtual Private Network), as configured through F5 BIG-IP Access Policy Manager (APM) Network Access, creates an encrypted tunnel between the remote client and the internal network. This ensures data privacy in transit and provides controlled remote access, satisfying both requirements stated in the question.

GRE (Generic Routing Encapsulation) is a tunneling protocol that encapsulates packets but does not include native encryption, so it does not ensure data privacy without an additional encryption layer such as IPsec.
