Currently their internet is via a cable modem and a Linksys wireless router using private IP space on the inside. Can the ASA 5505 work in site-to-site VPN mode behind their existing router?? Or does it have to become the front-end to the internet for that user?? If it can work behind the router, can someone tell me the general steps to accomplishing this. Thank you very much.</P> Sat, 22 Feb 2020 07:18:54 GMT https://community.cisco.com/t5/network-security/asa-behind-firewall/m-p/1078340#M963460 keithknowles 2020-02-22T07:18:54Z Re: ASA Behind Firewall https://community.cisco.com/t5/network-security/asa-behind-firewall/m-p/1078341#M963461 <HTML><HEAD></HEAD><BODY><P>Yes ASA 5505 can work behind the exixting Linksys router. please make sure of the following:</P><P></P><P>1) The isakmp policies match on the Linksys and ASA.</P><P></P><P>2) The crypto access lists reciprocate for both routers.</P><P></P><P>3) The crypto maps are properly defined and placed on the correct interface.</P><P></P><P></P></BODY></HTML> Wed, 05 Nov 2008 15:13:29 GMT https://community.cisco.com/t5/network-security/asa-behind-firewall/m-p/1078341#M963461 vmoopeung 2008-11-05T15:13:29Z
