      Hello,

      I'm currently setting a pfSense configuration. I have set up the firewall and the client according to the tutorial in http://www.huijgen.com/tunnel/ and I'm facing some issues.

      The phase 1 works and the tunnel is established. As soon as I try to ping a remote machine from either side, I have the following log in /var/log/ipsec.log:

      
2011-03-18 16:32:56: ERROR: no configuration found for 192.168.0.55.                                                                                                                
2011-03-18 16:32:56: ERROR: failed to begin ipsec sa negotication. 

      I have put racoon in debug mode, and it complains about the configuration being passive:

      
2011-03-18 16:36:10: DEBUG: in post_acquire

2011-03-18 16:36:10: [192.168.0.55] DEBUG2: Not matched.                                                                                                                            
2011-03-18 16:36:10: [192.168.0.55] DEBUG: no remote configuration found.                 

      So I removed the passive on in /var/etc/racoon.conf.

      It helped in establishing the phase 2 SA but pinging still does not work. The phase 2 negociation restarts every 12 seconds or so:

      I'm using the shrew VPN client in version 2.1.7, both on linux and Windows XP with the same symptoms.

      I have also 2 other VPN tunnels (gateway to gateway) working fine on this machine.

      Any clue ?

        I'm having the same problem.

        My tunnel is between two pfSense 2.0 RC1 boxes but one has a dynamic IP.

        I did find that the "sainfo" section of racoon.conf doesn't look right if I only have one phase 2

        
sainfo   anonymous
{
        remoteid 2;
        encryption_algorithm aes 256;
        authentication_algorithm hmac_sha1;

        lifetime time 3600 secs;
        compression_algorithm deflate;
}

        If i have two phase 2 entries that section shows the network info:

        
sainfo subnet 10.1.0.0/16 any anonymous
{
        remoteid 2;
        encryption_algorithm aes 256;
        authentication_algorithm hmac_sha1;

        lifetime time 3600 secs;
        compression_algorithm deflate;
}

        But i still can't pass data between the two:

            If you're on a current snapshot, try setting the Policy Generation to Unique, and Proposal Checking to Obey in the mobile phase 1 settings.

              i'm not sure why at the end of the log it says "no configuration found for…" and it shows shrew's ip even though it set everywhere to identify remote clients by key identifier
              shrew says that "tunnel enabled" but nothing goes through

                      Can you try with policy unique and proposal checking strict.
                      I was getting the same errors as you and that worked for me.

                      Also set NAT-T to force

                          yes, the same error, I use a gateway who use dynamic IP in the another side, in gateway, the log show tunnel established, in pfsense rc2.0 the ipsec log show tunnel established too, but when I ping from pfsense or dynamic ip gateway, pfsense give me the log following:

                            We've been good with mobile access (on one WAN only though) using SHREW and windows vista/7 64 bit.  I posted the links/tweaks here: http://forums.smallnetbuilder.com/showpost.php?p=34663&postcount=7

                            I had the racoon configuration errors too, but changing policy gen to "unique" fixed the error.  I followed the guide posted pretty much to the letter otherwise.

                            Btw, SHREW may show tunnel established but if you see no security associations established (Network Tab in VPN Connect Window) when you attempt to access a VPN IP..then you're going nowhere.

                              I had this same problem. Here's how I solved it: https://sites.google.com/a/vorkbaard.nl/dekapitein/tech-1/how-to-set-up-ipsec-tunneling-in-pfsense-2-0-release-for-road-warriors

                              Sorry for posting the link twice.
