What is IKEv2?
IKEv2 (Internet Key Exchange version 2) is a VPN encryption protocol responsible for request and response actions. It handles the SA (security association) attribute within an authentication suite called IPSec.
What is PRF Sha?
The configuration is similar to the IKEv1 policy, the only new command is prf sha. PRF is the Pseudo Random Function algorithm which is the same as the integrity algorithm.
What is site to site VPN?
A site-to-site virtual private network (VPN) refers to a connection set up between multiple networks. This could be a corporate network where multiple offices work in conjunction with each other or a branch office network with a central office and multiple branch locations.
What is Sysopt connection permit VPN?

What is remote access VPN?
Remote Access VPN policy contains the connection profiles targeted for specific devices. These policies pertain to creating the tunnel itself, such as, how AAA is accomplished, and how addresses are assigned (DHCP or Address Pools) to VPN clients. They also include user attributes, which are identified in group policies configured on the Firepower Threat Defense device or obtained from a AAA server. 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.
What is AnyConnect profile?
An AnyConnect client profile is a group of configuration parameters stored in an XML file that the client uses to configure its operation and appearance. These parameters (XML tags) include the names and addresses of host computers and settings to enable more client features.
What is Cisco AnyConnect Secure Mobility?
The Cisco AnyConnect Secure Mobility client provides secure SSL or IPsec (IKEv2) connections to the Firepower Threat Defense device for remote users with full VPN profiling to corporate resources. 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.
Can Firepower Threat Defense resolve IP addresses?
Without DNS, the devices cannot resolve AAA server names, named URLs, and CA Servers with FQDN or Hostnames. It can only resolve IP addresses.
Why create a VPN profile?
You can create a remote access VPN connection profile to allow your users to connect to your inside networks when they are on external networks, such as their home network . Create separate profiles to accommodate different authentication methods.
Where does remote access VPN problem originate?
Remote access VPN connection issues can originate in the client or in the Firepower Threat Defense device configuration. The following topics cover the main troubleshooting problems you might encounter.
How to use a VPN on a computer?
Step 1. Using a web browser, open https://ravpn-address , where ravpn-address is the IP address or hostname of the outside interface on which you are allowing VPN connections. You identify this interface when you configure the remote access VPN. The system prompts the user to log in. Step 2.
How to complete a VPN connection?
To complete a VPN connection, your users must install the AnyConnect client software. You can use your existing software distribution methods to install the software directly. Or, you can have users install the AnyConnect client directly from the Firepower Threat Defense device.
What is AnyConnect client profile?
AnyConnect client profiles are downloaded to clients along with the AnyConnect client software. These profiles define many client-related options, such as auto connect on startup and auto reconnect, and whether the end user is allowed to change the option from the AnyConnect client preferences and advanced settings.
Where is change of authorization policy configured?
Most of the Change of Authorization policy is configured in the ISE server. However, you must configure the FTD device to connect to ISE correctly. The following procedure explains how to configure the FTD side of the configuration.
What is Cisco ISE?
Cisco ISE has a client posture agent that assesses an endpoint's compliance for criteria such as processes, files, registry entries, antivirus protection, antispyware protection, and firewall software installed on the host. Administrators can then restrict network access until the endpoint is in compliance or can elevate local user privileges so they can establish remediation practices. ISE Posture performs a client-side evaluation. The client receives the posture requirement policy from ISE, performs the posture data collection, compares the results against the policy, and sends the assessment results back to ISE.
What certificates are needed for AnyConnect?
Certificates are essential when you configure AnyConnect. Only RSA based certificates are supported in SSL and IPSec. Elliptic Curve Digital Signature Algorithm certificates (ECDSA) are supported in IPSec, but it's not possible to deploy new AnyConnect package or XML profile when ECDSA based certificate is used. It means that you can use it for IPSec, but you will have to predeploy AnyConnect package and XML profile to every user and any change in XML profile will have to be manually reflected on each client (bug: CSCtx42595 ). Additionally the certificate should have Subject Alternative Name extension with DNS name and/or IP address to avoid errors in web browsers.
Can VPN traffic come from pool?

A virtual private network (VPN) connection establishes a secure tunnel between endpoints over a public network such as the Internet. This chapter applies to Remote Access and Site-to-site VPNs on Firepower Threat Defense devices.
What is remote access VPN?
Remote access VPNs are secure, encrypted connections, or tunnels, between remote users and your company’s private network. The connection consists of a VPN endpoint device, which is a workstation or mobile device with VPN client capabilities, and a VPN headend device, or secure gateway, at the edge of the corporate private network.
How does a VPN work point to point?
In a point-to-point VPN topology, two endpoints communicate directly with each other. You configure the two endpoints as peer devices, and either device can start the secured connection.
Why use PKI in VPN?
Using a PKI improves the manageability and scalability of your VPN since you do not have to configure pre-shared keys between all the encrypting devices. Instead, you individually enroll each participating device with a CA server, which is explicitly trusted to validate identities and create an identity certificate for the device. When this has been accomplished, each participating peer sends their identity certificate to the other peer to validate their identities and establish encrypted sessions with the public keys contained in the certificates. See Certificate Enrollment Objects for details on enrolling FTD devices.
How to validate a peer's certificate?
In order to validate a peer’s certificate, each participating device must retrieve the CA's certificate from the server. A CA certificate is used to sign other certificates. It is self-signed and called a root certificate. This certificate contains the public key of the CA, used to decrypt and validate the CA's digital signature and the contents of the received peer's certificate. The CA certificate may be obtained by:
