Creating Site to Site VPN Tunnel using Cisco ASA with Dynamic IP

Hi there,

Our main office has Cisco 5520 firewall behind dedicated internet line (fixed outside facing ip) and I have been tasked with setting up a new office but due to geographical constraints we have only been able to aquire a home broadband like DSL internet connection (dynamic IP). I have a Cisco 5505 ASA and would like to create a VPN tunnel between 2 offices using said devices. Can you please let me know the best and easy way to set this up. Thanks in advance for all your contributions.

Have you tried to use the ASA VPN Wizard ? Here is a sample configuration between static and dynamic VPN peer address:

http://www.cisco.com/en/US/products/ps6120/products_configuration_example09186a00805733df.shtml

For dynamic to static VPN tunnel, the dynamic end needs to initiate the connection towards the static end. Because the dynamic end changes IP all the time, the static end would not know what the IP, hence the dynamic end needs to initiate the connection towards the static to bring up the VPN tunnel

One other option would be to add in a DNS client such as Dyn DNS or other 3rd party. This would give you a host that will monitor the IP changes and adjust accordingly. Then all you would have to do is source it to that IP.  For now try the above.

If the IP of the remote end changes all the time, you can use DynDns.com (http://dyn.com/dns/dyndns-pro-free-trial/) to simulate a fixed IP.

Also, check to see if your "dynamic" IP changes much. Mine changes maybe once every couple of years, so I treat it as fixed and connect the other ends normally. I have to change the setups every couple of years for the new IP address.
