Thank you for the reply, I just found out that we are using DMVPN. &nbsp; Does that change things as far as what I need to to get the new site up and running? &nbsp;

I have a Cisco 1811 from one of our offices that has been shut down. &nbsp;I would like to now use this router at a new site. &nbsp;The old site used DHCP and the new site can use the same address scheme. &nbsp;The tunnel information should be the same. &nbsp;I know that I need to change the wan interface to the new wan address of the new site. &nbsp;What other settings would I need to change to get this working? &nbsp; I am testing it from my home and have been unable to get the tunnel up. &nbsp;I connected my cable modem to FE0 and changed the ip, and it connects okay. &nbsp;The remote sites use our DNS so that wouldn't need to be changed. &nbsp;I plugged into one of the ports and received an IP. &nbsp;Any tips on getting the tunnel up, is there a command I need to run on the router on the other end? &nbsp;Thanks.

Transfer VPN device to new site

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.
