Bond modes offered to the edge fleet.

Legacy Duplicate

Engarde-based duplicate tunnel. Kept for compatibility; use Duplicate All Wired for the kernel dataplane.

duplicate

Duplicate Critical Only

Only traffic_rule matched critical flows use the tunnel; other traffic exits raw by per-flow hashing.

critical

Bonding (per flow)

Pins each TCP/UDP flow to one wired WAN. Aggregate throughput can use both WANs, single flows do not.

bond_flow

Primary + Failover

Uses the selected primary wired WAN through the tunnel, then backup wired WAN, then cellular.

failover

Simple Failover (no tunnel)

Plain dual-WAN failover without engarde or wg-data. Management tunnel stays available.

notunnel_failover

Duplicate All Wired

Kernel VXLAN active-backup receive path with a best-effort WAN2 transmit mirror.
