Concentrator 3005 to Linksys RV082 VPN

Unanswered Question
Apr 3rd, 2007

Hi guys,

We are trying to setup a Site-to-site VPN using a Cisco Concentrator 3005 and a Linksys RV082. I am quite positive we are having a configuration problem but not entirely sure what is it. My biggest problem is how the RV082 divides everything into phases and the Concentrator does not making it hard for us to match up the two. When I try and connect to the concentrator I get the following in my RV082 log:

Anybody with experience setting this up? Any ideas regarding this would be much appreciated.

Thanks

Petter

While my experience with the RV082 is a bit limited, I believe that we can make some observations about your issue. In general we can describe the IPSec negotiations as being in 2 phases: Main Mode and Quick Mode. Main Mode is oriented to negotiating the ISAKMP key exchange and establishing a secure encryption key and the first set of Security Associations (SA). This message:

Apr 3 13:39:58 2007 VPN Log [Tunnel Negotiation Info] Main Mode Phase 1 SA Established

indicates that Main Mode was successful. After Main Mode IPSec negotiates Quick Mode which is oriented to negotiating Security Associations for IPSec. Your messages indicate that this is not working.

I suggest that you compare the parameters configured on your 3005 and the parameters configured on the RC082. I suspect that something is not matching up.
