      I am using 1.0/1.0.1… I had the remote end allow pings to an endpoint and will know by tomorrow if that helped.

        No, that´s not the problem, maybe a bug

          Then it would have to be a bug existing pre 1.2b.

          Heiko do your tunnels eventually come back by themselves without your intervention? Mine do but sometimes it is minutes and sometimes hours… doesn't seem to be any rhyme or reason. If I at least had settings for my customer on the otherside to try...or I could suggest they get rid of their cisco equipment and replace with pfsense :P

            It is not a bug.  I run IPSEC all over the place and have no issues.

              Sorry Scott, maybe a feature… ;) I don´t know...

              after the update from the snapshot 04-06-2007 the problems coming back. Before this update all ipsec tunnels worked fine. (Snapshot  2007-06-03 nighlty build)

              After the update two tunnels came back only with intervention!! Another tunnel comes back after a few minutes.....
              For me the "ipsec" is working like the snapshot before you made the changes in the cvs (2007-06-02 -ipsec-racoon etc.)

              Sorry

                Are all tunnels running the same version?  If not, you might try upgrading them all to 1.2-BETA-1 or a newer snapshot.

                  No, not all the tunnels are on the same version, the problems are on tunnels from openswan  to pfsense.
                  Although this tunnels worked fine before i upgraded to the  snapshot from 2007-06-04…...

                    Do you fixed your tunnel problems?

                      Cheech it is probably the Cisco that is the problem.

                        I think, now i have a stable config between pfsense carp <–> pfsense carp and also pfsense carp <--> openswan ipsec. I will make another  test tommorrow, but currently the tunnels are all up and running great....

                        I need two rules on the wan , ESP permit and UDP 500 permit to the wan carp, then it runs as it should...

                          I had a similar problem and the exact same solution. It looks like pfsense isn't adding the rules to allow the carp address just the wan address

                          I guess I wasn't being stupid after all  ;D

                              I have found interoperability issues between pfsense and non-pfsense routers when using IPSEC. I might be wrong but I think pfsense is intended primarily for pfsense <> pfsense. Unfortunately it is not always possible /practical to convince the other side to switch to pfsense. I have seen problems with connectivity between pfsense to Dlink, Linksys and Cisco VPN products. Sometimes simply solved by deleting the SPD.

                                IPsec is IPsec. If you have it properly configured on both ends it'll work fine. If you have to delete SPD's, you probably have mismatched lifetimes, and/or a data transfer-based lifetime (i.e. expire after X KB) configured, the latter of which you can't configure on the pfsense side so you cannot use.

                                It can be difficult to properly configure IPsec to match what pfsense allows you to configure, especially on devices as flexible (and hence complex) as Cisco. pfsense to pfsense or m0n0wall is dead simple because the config options are simple to get matched properly.

                                As for Dlink and Linksys, I haven't worked with Dlink IPsec, or heard of others who have, but Linksys IPsec is widely known to be a joke. Maybe their more recent equipment and/or firmware is better, but when it has come up on the m0n0wall list several times in the past, numerous people have stated those things never work reliably for them regardless of what they're connecting to.

                                    Today all tunnels are up and runs fine, between carp pfsense <–> carp pfsense and carp pfsense <--> Openswan ipsec. The Openswan config is a little bit tricky....but it runs  :D  :D  :D

                                    This is the working ipsec.conf here:

                                    left=xxx
                                    leftnexthop=%defaultroute
                                    leftsubnet=192.168.10.0/255.255.255.0
                                    right=219.6.85.88
                                    rightsubnet=192.168.11.0/255.255.255.0
                                    rightnexthop=%defaultroute
                                            ike=aes128-sha-modp1536,aes128-sha-modp1024,aes128-md5-modp1536,aes128-md5-modp1024,3des-sha-modp1536,3des-sha-modp1024,3des-md5-modp1536,3des-md5-modp1024
                                            esp=aes128-sha1,aes128-md5,3des-sha1,3des-md5
                                            ikelifetime=1h
                                            keylife=8h
                                            dpddelay=30
                                            dpdtimeout=120
                                            dpdaction=hold
                                            pfs=yes
                                            authby=secret
                                            auto=start

                                    Have fun.., but do not forget the rules on the wan at this time (ESP and UDP500 to the WAN CARP)

                                      Wow, so they're actually stable? I cringe at the thought of supporting 40 Linksys VPN boxes.  ;D  I've tried the BEFVP41, granted it was probably 5 years ago, but at the time it didn't work reliably at all no matter what I connected it to.

                                      I think I still have it on a shelf around here somewhere, maybe it's time to give it another shot if for nothing other than the sake of documenting the proper way to configure one to connect to pfsense.
