Blocked GRE when connected via PPTP VPN



  • Hi,

    I have a quick question.
    When I connect with a client behind the pfsense to a VPN Server via PPTP I see that a GRE packet is blocked by the firewall.
    The VPN connection is working properly.
    I have no additonal rules in place so I think it´s the default rule.
    Now my question: Should I create a rule to let the GRE packets in?

    Thanks,
    Tobi

    If the VPN connection is working properly, this can probably be safely ignored. It may be that the server side is sending a GRE packet before the GRE state is active, but if the connection works normally after that log entry, I wouldn't worry about it.
