Presets

Presets provide different configuration options for a tunnel and its used interfaces.

Presets are stored in "presets.json" on both client and server installations. Some presets are not directly accessible in router packages, as some of them are redundant and only kept for compatibility.

Tunnel Presets

Preset Name	Friendly Name	Description
bonding	(Default) Bonding	The default bonding strategy. Uses least amount of interfaces if possible, ranging from best to worst.
bondingDistribute	Bonding with enforced distribution	Bonding with enforced distribution. This mode can increase latency jitter and degrade performance in situations where an excellent line (e.g., fiber) is mixed with a mediocre to bad line (e.g., bad 4G).
duplication	Packet Duplication	Attempts to send each data fragment twice using different interfaces. Packet duplication is not guaranteed (e.g. if only one WAN interface is available)
duplication2	Packet Duplication 2X	Like packet duplication, but each data fragment is used over up to three interfaces.
failover	Seamless failover	Seamless or smart failover only uses one interface at a time. If the primary interface goes down, a secondary interface will be used without interrupting any connections.
loadbalancer	Load Balancing Mode	Experimental Load Balancing mode. Not recommended.

Channel Presets

Preset Name	Friendly Name	Description
mobileAggressive	Optimize for Speed	This default preset is a general-purpose configuration suitable for most lines (4G, DSL, etc), with a fair tolerance for packet loss and latency.
ethernet	Default Ethernet	A preset for direct ethernet connections, very sensitive to latency and packet loss.
genericTCP	TCP Mode	Utilizes TCP instead of UDP. Higher throughput rate at the cost of latency. Useful in scenarios where UDP is throttled or blocked.
lowLatency	Low Latency	Similar to ethernet preset, but with higher tolerance for packet loss
mobile	Mobile	A general purpose preset for mobile connections favouring latency
mobileLowLatency	Optimize for Latency	Another preset for mobile connections with an even higher focus on latency
