What is mlvpn

mlvpn is a piece of software, similar to OpenVPN, which can create a network tunnel between two computers.

mlvpn encapsulates network packets, using UDP and send them encrypted over the internet to another location.

The primary use of mlvpn is to create bonded/aggregated network links in order to benefit from the bandwidth of multiple links.

Still, mlvpn can be used as a regular secure tunnel daemon, capable of handling failover scenarios.


  • Bandwidth aggregation of multiple internet connections
  • Automatic failover, without changing IP addresses or interrupting TCP connections in case of a failure
  • Encrypt and authenticate connections using libsodium.
  • Hot configuration reload (by signaling SIGHUP)
  • Scriptable monitoring
  • Remote monitoring through UNIX socket or TCP/HTTP socket. (JSON API)
