      when there's a tunnel created that makes use of it :P

      I did only some lousy tests with my existing config which consists of a few Lancom 1811 -> pfsense's racoon. This config works great, but if I just add deflate to the parameters on the Lancom sites, the parties can't negotiate.
      I'm aware that this could be a problem with the Lancom devices, but it's unlikely. As far as I know the setting "compression_algorithm deflate;" in racoon.conf is mandatory.. if a specific tunnel was to be configured for (optional) ipcomp or not, it would have to be set for the SPD.
      I don't think that anything has changed in this domain since my thread a few months ago as I have watched the activity about ipsec changes on redmine… But if it did, I'm sorry to have brought something up which already exists..

        Have you tried Jimp's actions?

        –-edited---
        I'd be interested in implementing this but it does not look feasible without being able to test it.

            Yes, it is successfully negotiate with both ipcomp turned on and off but only if pfSense acts as a server for Mobile Client. I did not manage to make shresoft client to work with pfSense in site-to-site tunnel mode.

              Hi,

              this is great news. If you've gotten this far, I'm sure you'll succeed with the remaining site-to-site mode as well ;)

                Hi,
                I am afraid it's not about me, it is about shrewsoft client - it just does not want to negotiate in site-to-site mode and to be honest I do not see how it is expected to work using threwsoft client. You install it on your PC and vpn into the office, that works.
                As far as I understand you use other software/equipment, why don't we return to your set up?

                  Hi,

                  thanks for your reply.
                  I'm using several Lancom 1811 VPN gateways to build site-to-site tunnels with a central pfsense box.
                  This of course is a setup you can't test as long as you don't have such a device.

                  Is there no way to verify if a tunnel between 2 pfsense boxes is actually effectively using ipcomp?
                  If that works, it will work with the Lancoms too..

                    Or do you have any other hardware vpn gateway which you could use for testing?
                    When I setup ipcomp (using deflate) on the Lancoms, they won't connect if the other side isn't using it.

                      I have configuration that allows two pfSense boxes to set up tunnel with ipcomp in SPDs but I do not know a method to prove that ipcomp is actually 'in use' when passing traffic as I do not see any compression.

                        We can try to configure pfSense in the way I did and if it works with Lancoms then we can think about adding this feature to GUI.

                          Okay, good idea.
                          How would we do this?
