      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

                ok, got it working! on the shrew side nat-t should be set to "force-rfc", "force-draft" doesn't work.

                  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:

                  and no traffic between gateway and pfsense!
                  I try policy "unique" proposal "obey", and policy "unique" and proposal "strict",  error is the same

                    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.
