Site to Site VPN - Cisco ASA 5540 to Sonicwall TZ200

Posted on 2011-09-11
Last Modified: 2012-05-12
I am have a Cisco ASA 5540 with a static ip (Outside Interface) and Sonicwall TZ200 with a dynamic ip (Outside Interface). The Sonicwall firewall is set to use aggressive mode and I know I will need to mirror the phase configurations. However, any sample configurations would be helpful for the Cisco ASA 5540.

Thanks in advance.

dynamic map on your ASA should do the trick.

Do you have a config sample I can use as a template?

Try the link i sent you above. Without your IP information I can't really reproduce a config that actually works, but the URL above has all the information you need to configure you ASA that is establishing a site to site with your Sonicwall that has a dynamic ip.

Do I need to set mode to aggressive on the Cisco ASA if it is already on the Sonicwall?

Your Sonicwall will be the initiator and needs to be in aggressive mode. The Cisco ASA needs to be in aggressive mode as well.
