ASA S2S Tunnel Error

We are replacing a Linksys RV042 VPN endpoint with an ASA 5505 Security Plus appliance.

Having problems establishing one of our site-to-site VPN tunnels (unfortunately I do not know what the other device is, and all I can do for now is replicate the settings that were present for this tunnel on the ASA).

This is what I'm receiving:

      AAA retrieved default group policy (M-Tunnel) for user = Endpoint_IP
      Group = Endpoint_IP, IP = Endpoint_IP, PHASE 1 COMPLETED
      Group = Endpoint_IP, IP = Endpoint_IP, All IPSec SA proposals found unacceptable!
      Group = Endpoint_IP, IP = Endpoint_IP, QM FSM error (P2 struct &0xd5144720, mess id 0xf4ae87c3)!
      Group = Endpoint_IP, IP = Endpoint_IP, Removing peer from correlator table failed, no match!
      Group = Endpoint_IP, Username = Endpoint_IP, IP = Endpoint_IP, Session disconnected. Session Type: IKE, Duration: 0h:00m:00s, Bytes xmt: 0, Bytes rcv: 0, Reason: Phase 2 Mismatch
      Group = Endpoint_IP, IP = Endpoint_IP, Automatic NAT Detection Status: Remote end is NOT behind a NAT device This end is NOT behind a NAT device

*Endpoint_IP = WAN IP of Remote Gateway

I'm almost thinking I'm connecting to some sort of PPTP device not capable of IPSEC or not configured for IPSEC (Windows server?).

Any ideas; I'll hopefully find out tomorrow what I'm connecting to, but I'd like to get this solved ASAP.

What is strange was that the tunnel was up for some time (after we replaced the RV042 with the ASA, we confirmed the tunnel was up); when I checked back a few hours later, I noticed these events continually appearing in the syslog, and the tunnel not showing as up.

It is a PPTP tunnel and an ASA cannot be a PPTP server.

All IPSec SA proposals found unacceptable!

This is your problem. You need to find out what SA proposal the other device accepts and set them up on your Asa.
