      Still no replies from anyone but I am still attempting to help myself so here is what I'm doing and here are my results.

      One of the trunks that keeps going down is a cisco PIX. So I remove the 86400 lifetime from SA 2. and kept group on 2 "I also tried off".

      I get the exact same results.

      I will try tonight adding the lifetime back and removing the first lifetime.

        Hello,

        Racoon really doesn’t want to recieve a FQDN when it’s trying to create a connection with a shared key.
        Make sure the Cisco has the line

        • isakmp identity address in it’s config.

        Don’t forget to set your DH and PFS number at the same number as the Cisco.
        In the past i have had problems between pfsense and "cisco´s" with DPD.

        Regards
        Heiko

            can you post your ipsec tunnel config from pfsense-side, are both sides static?

            racoon: ERROR: not acceptable Identity Protection mode –> maybe an MD5 or SHA problem in your config?

                it looks OK, why do you choose "aggressive" mode and not main mode, did you try for phase 1 a lifetime "28800" and phase 2 "86400"?
                Do you have tested it with SHA not MD5 and what errors shows the pix log?

                  I choose all of the following because that is what was required by the monowall instructions.

                    If you have on both sides static ip´s please test this as the  last slight hope, sorry but I haven´t a pix at the moment to duplicate your test

                      FWIW, I've had success connecting to PIX's without using no-xauth and no-config-mode
                      eg-
                      isakmp key ******** address x.x.x.x netmask 255.255.255.255

                      I also didn't have
                      isakmp identity address
                      isakmp nat-traversal 20
                      in my config. Otherwise similar- 6.3(5) on a 506

                        I've found a confirmation of what heiko said about the identification mode with a preshared key, in the source code
                        ipsec_doi.c
                        /* In main mode with pre-shared key, only address type can be used. */
