Hello dear experts!<br />
One of my customers has an East Coast office, and and a West Coast Office. I am at the East Coast office.<br />
We use two Cisco ASA 5505 Firewalls to VPN our networks together. Each network has a domain controller, and both offices are in the same domain. <br />
The challenge: &nbsp;The West Coast office is moving from one building to another, with a new ISP. I have been tasked with generating step by step documentation so that the business owner in the West Coast can change the settings of the ASA units at both ends. I looked into doing this through ASDM 6.4, but I see that it seems that you cannot simply edit the peer IP address and connection name. <br />
Of course, I also need to show how to change the external IP address for the new locations static IP, but that is straightforward in ASDM (Launch ASDM-&gt;Configuration-&gt; Interfaces-&gt;Outside-&gt;Edit-<wbr />&gt;Change External IP to the new one, please correct me if I am wrong). My question is: 1) Can you use ASDM to change Site-to-Site IP adress VPN settings, without having to delete the entire VPN? I am attaching a file so you can see how the Peer IP Address and connection name fields are not editable, as far as I could tell.

Cisco PIX is a dedicated hardware firewall appliance; the Cisco Adaptive Security Appliance (ASA) is a firewall and anti-malware security appliance that provides unified threat management and protection the PIX does not. Other Cisco devices and systems include routers, switches, storage networking, wireless and the software and hardware for PIX Firewall Manager (PFM), PIX Device Manager (PDM) and Adaptive Security Device Manager (ASDM).

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.

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.

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.
