The preshared key I created is not working when I try to test connect as the vpn user with the preshared key I created. I want to start over and try again, but I do not want to remove the other existing and important tunnel-groups. What is the command syntax to remove a VPN user or a tunnel-group if that is the more accurate request. It would actually be preferable to be able to change or edit or replace the preshared key and leave the remainder of the config intact, but if that is not possible then I would like the syntax to remove the group so I can try again. If you want to be really helpful you can also paste in the syntax to create a new tunnel-group correctly in the event I made an error. I used the deprecated command from the 501 series, but it did add it and so I thought it would work, but the client log indicates an incorrect key.<br />

Thank you,<br />

Cisco ASA 5510 how do I remove a specific tunnel-group I created that is not working and leave the others intact.

A virtual private network (VPN) is a network that uses a public telecommunication infrastructure, such as the Internet, to provide remote offices or travelling users access to a central organizational network securely. VPNs encapsulate data transfers using secure cryptographic methods and other security mechanisms to ensure that only authorized users can access the network and that the data cannot be intercepted.

Internet Protocol Security (IPsec) is a protocol suite for secure Internet Protocol (IP) communications by authenticating and encrypting each IP packet of a communication session. IPsec includes protocols for establishing mutual authentication between agents at the beginning of the session and negotiation of cryptographic keys to be used during the session. IPsec can be used in protecting data flows between a pair of hosts (host-to-host), between a pair of security gateways (network-to-network), or between a security gateway and a host (network-to-host). IPsec is an end-to-end security scheme operating in the Internet Layer of the Internet Protocol Suite.

Hardware-based firewalls provide more sophisticated protection for inbound and outbound traffic than the simple Windows software firewall or the basic NAT firewalls found in routers. These devices implement techniques such as stateful packet inspection, deep packet inspection, and content filtering; and may include built-in antivirus and anti-malware protection.
