Introduction

This document describes how to configure the deploying of Remote Access Virtual Private Network (RA VPN) on Firepower Threat Defense (FTD) managed by the on-box manager Firepower Device Manager (FDM) running version 6.5.0 and above.

Background Information

Unable to configure FTD via FDM for Anyconnect clients to connect to the external interface while management is opened via the same interface. This is a known limitation of FDM. Enhancement request CSCvm76499 has been filed for this issue.

Prerequisites

Cisco recommends that you have knowledge of RA VPN configuration on FDM.

Troubleshoot

This section provides information you can use to troubleshoot your configuration.

A device also provides a default connection profile named DefaultWEBVPNGroup. The connection profile that is configured using the wizard appears in the list.

What is Firepower Threat Defense?

The Firepower Threat Defense device supports applying user authorization attributes (also called user entitlements or permissions) to VPN connections from the external RADIUS server that are configured for authentication and/or authorization in the remote access VPN policy.

Without a previously-installed client, remote users can enter the IP address of an interface configured to accept clientless VPN connections in their browser to download and install the AnyConnect client. The Firepower Threat Defense device downloads the client that matches the operating system of the remote computer. After downloading, the client installs and establishes a secure connection. In case of a previously installed client, when the user authenticates, the Firepower Threat Defense device, examines the version of the client, and upgrades the client if necessary.

What is the only VPN client?

The only supported VPN client is the Cisco AnyConnect Secure Mobility Client. No other clients or native VPNs are supported. Clientless VPN is not supported for VPN connectivity; it is only used to deploy the AnyConnect client using a web browser.

What is TLS in security?

When the client negotiates a connection with the security appliance, the client connects using Transport Layer Security (TLS), and optionally, Datagram Transport Layer Security (DTLS). DTLS avoids latency and bandwidth problems associated with some SSL connections and improves the performance of real-time applications that are sensitive to packet delays.
