L2L between Cisco Router 1841 and Cisco Asa 5505

leonardo.calabretta · ‎01-03-2014

I'd like to configure a VPN Lan To Lan between my customer and my office. My customer have Cisco Router 1841 and I have Cisco ASA 5505.

I've 3 vlan on my switch L3 Cisco:

Server -> 192.168.33.254

Client -> 192.168.30.254

Wireless -> 192.168.31.254

My ASA have an Ip only on two Vlan:

Client -> 192.168.30.253

Wireless Guest -> 192.168.32.253

Every Computer on each Vlan has 192.168.xx.254 as default gateway and on my L3 Switch I have "0.0.0.0 0.0.0.0 192.168.30.253".

The tunnel does not want come up and I have this error on my ASA:

Jan 03 09:41:08 [IKEv1]Group = Public_IP_Customer, IP = Public_IP_Customer, QM FSM error (P2 struct &0xcc49d048, mess id 0xc361618)!

Jan 03 09:41:08 [IKEv1]Group = Public_IP_Customer, IP = Public_IP_Customer, Removing peer from correlator table failed, no match!

Jan 03 09:41:08 [IKEv1]Group = Public_IP_Customer, IP = Public_IP_Customer, Session is being torn down. Reason: Lost Service

My customer have only 1 lan, 10.0.0.0/16 but it have 2 Outside interface on router. This is a very large subnet then I nat that with subnet: 172.0.101.0/24. This is the router configuration:
