Side to Side VPN fails because of wrong config but config is correct



  • Hi together,

    I have the following issue:
    Ich try to connect pfSense to AVM Fritz!Box of a friend.
    The problem ist: it doesn't connect.
    If I look to the logs, it says:

    The interesting thing is:
    I have configured AES 256, SHA512, DH 1024 in Phase 1
    and
    AES256, SHA512, PFS Group 2 (1024) with ESP on Phase 2.
    Nothing else configured,.
    I also tried it without PFS.

    Any ideas where this issue can come from?
    I already restarted the IPSec service (with restart AND with stopping and starting it again).
    I also tried to fix this with rebooting the whole sense but that didn't work :-(

    EDIT: If i change config it seems not to be activated in spite of restarting the service via Stop -> Start.

    Thanks for your answers!

    Greetings

  • I could solve the problem:
    The configured remote address was wrong.
    But pfsense seems to have a standard config, because in the log it says, that pfsense is using %any config or something.

    Is that normal?

    Thanks!
