ipsec port 1024 problem

  • There are 2 tunnels both work.
    after some time one stops. and changes the port from 4500 to 1024
    will work only after reboot
    I tried to re-create the settings does not help, work about 2 weeks.

    Any ideas how to fix it?
    2.4.3-RELEASE-p1  previous versions have the same problem.

    That is probably what the far side used to contact you. pfSense will reply back to whatever port the far side used, since it was probably run through NAT or had some other similar translation done along the way.

    There may not be anything you can do about that on your side, the far side probably needs to fix whatever is changing that port.
