A. The Cisco IPSec VPN Client version 3.x did not had the virtual adapter in it. This caused the protocols having the IP address configuration information in the payload (example FTP) to face several issues.

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.

- Cisco recommends that you have knowledge of these topics: 1. Basic VPN, TLS and IKEv2 knowledge 2. Basic Authentication, Authorization, and Accounting (AAA) and RADIUS knowledge 3. Experience with Firepower Management Center
Components Used
- The information in this document is based on these software and hardware versions: 1. Cisco FTD 6.2.2 2. AnyConnect 4.5
Configuration
- 2. Remote access wizard
1. Go to Devices > VPN > Remote Access > Add a new configuration. 2. Name the profile according to your needs, select FTD device: 1. In step Connection Profile, type Connection Profile Name, select Authentication Server and Address Poolswhich you have created earlier: 1. Click o…
Connection
- To connect to FTD you need to open a browser, type DNS name or IP address pointing to the outside interface, in this example https://vpn.cisco.com. Youwill then have to login using credentials stored in RADIUS server and follow instructions on the screen. Once AnyConnect installs, you then need to put the same address in AnyConnect window and click Connect.

- Currently unsupported on FTD, but available on ASA: 1. Double AAA Authentication 2. Dynamic Access Policy 3. Host Scan 4. ISE posture 5. RADIUS CoA 6. VPN load-balancer 7. Local authentication (Enhancement: CSCvf92680 ) 8. LDAP attribute map 9. AnyConnect customization 10. AnyConnect scripts 11. AnyConnect localization 12. Per-app VPN 13. SCEP proxy 14. WSA in…
Security Considerations
- You need to remember that by default, sysopt connection permit-vpn option is disabled. This means, that you need to allow traffic coming from pool of addresses on outside interface via Access Control Policy. Although the pre-filter or access-control rule is added intending to allow VPN traffic only, if clear-text traffic happens to match the rule criteria, it is erroneously permitted…
