Hi folks, question about DPD in a road-warrior configuration: Is it sufficient for either side to answer DPD packets, or should both sides run their own DPD in parallel, independent from the DPD sent by their peer?
Reason for asking is, I have the impression that some home office gateways keep track only of the outgoing traffic (laptop to VPN gateway) to keep their stateful firewall alive, ignoring incoming DPD traffic sent by the VPN gateway. Every helpful comment is highly appreciated Harri
