*SOLVED* pfSense to Openswan 2.6 IPSec



  • Hello All,

    –-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

    #Edit

    Strictly by trial and error I got this resolved.

    1. On the Openswan config I had the following line in it
      auth=ah (also tried auth-esp)
      1a) After removing this line all together -> default of blank which is ESP the following lines disappead in logs on both IPSec servers, and the site to site IPSec is stable.
      Almost appears that one of the two endpoints finally gave up staying connected on account of this misconfig,on my part,I guess?

    Updated pfSense from 2.1.4-RELEASE(amd64) to pfSense-2.2.4-RELEASE(amd64) a few days ago and had quite a time getting the IPSec site to site to connect and ended up having to add about 3 more lines on the Openswan-2.6 remote end (Debian) server to get traffic passing as it is suppose to.

    Everything appeard ok....but;
    After about 6-8 hours the connection stops functioning. NO pings to remote end either direction. A simple fix is to ping from the pfSense(which shows green in the STATUS>IPSec connections) to the Openswan remote end,immediatley traffic is passing again.

    Here is a paste of the Openswan log:

    Also even after traffic is passing the following is appearing on the Openswan server:

    Before updating pfSense never had any trouble with connection,(about 2 years running) but something tells me I need to add more lines to the Openswan conn . config file.

    Anyone have any ideas what these logs are saying?

    Thank You,
    Barry
