Hello. I have been getting these messages in the log. What would be the cause of this and how can I block it?
Thank you,
Juraj.

    Hi @cpg_juraj,

    These logs appear because of Dead Peer Detection (DPD).

    When Dead Peer Detection (DPD) is enabled, the feature uses packets "R_U_THERE" and "R_U_THERE_ACK" to check peer's aliveness.



    Best regards,
    Emily
