IPSec L2L issue.

Unanswered Question

Hello.

I have a hub-spoke vpn solution, using ASA with software 8.0(3).

I have installed the last spoke, an ASA5505 like all others, but the tunnel does not come up!

Using debug I can get this message:

Dec 17 01:56:04 [IKEv1]: IP = X.X.X.X, Duplicate Phase 1 packet detected. Retransmitting last packet.



All spoke are ASA5505 with the same configuration for isakmp and IPSec.


Any idea?

Thanks.

Andrea.

Andrea,


Based on the debugs, it looks like the IKE packets are being blocked somewhere along the path between the Hub and Spoke. Make sure that the IKE and IPSEC Ports/Protocols are not blocked anywhere between the ASA5505 and headend side.

One document points to the key being invalid, another indicates the crypto ACLs aren't properly setup. Try re-entering the key on the spoke to verify it matches with the hub. Also double-check the crypto and nonat ACLs on both sides to verify they look proper.


Hope this helps, rate if it does,

JB
