What is Dead Peer Detection (DPD)?
Dead Peer Detection (DPD) is a VPN feature that detects when the other side of a VPN tunnel is no longer responsive.
Without DPD, your VPN connection could silently fail without you noticing.
DPD keeps things running smoothly by checking the peer's status and cleaning up dead tunnels so they can reconnect automatically.
