nettunnel

nettunnel is an omz-net-lib extension allowing two mutually trusting peers to communicate efficiently over a single TCP connection. This usage of virtual connections reduces round-trip times during connection establishment.

Configuration

Configuration ID: ntun

Name	Type	Description	Required	Default value
enable	boolean	Whether this plugin is enabled.	no	true
alwaysEnableServer	boolean	Always enable and start the server implementation, regardless of whether the feature set contains ntun.server.plain or ntun.server.tls.	no	false
alwaysEnableClient	boolean	Always enable and start the client implementation, regardless of whether the feature set contains ntun.client.plain or ntun.client.tls.	no	false
baseImpl	string	The underlying network implementation to use.	no	"nio"
maxPacketSize	number	The maximum protocol frame size.	no	16384
maxConcurrentConns	number	The maximum number of concurrent connections.	no	65535
sharedSecret	string	The shared secret for authentication. A value of null disables authentication.	no	null
encrypted	boolean	Use an encrypted connection for communication.	no	false
serverBindPort	number	(Server-only) The port to listen for TCP connections on.	no	NetTunnel.DEFAULT_PORT (1184)
serverParams	object	(Client-only) Server parameters to connect to.	~	null
serverParams.address	string	The server address.	yes	-
serverParams.port	number	The server port.	no	NetTunnel.DEFAULT_PORT
serverParams.localAddress	string	The local address to connect from.	no	none (system default)
useUpstreamServerParams	boolean	If true, use the default upstream server parameters of the proxy configuration for the values of serverParams. If both serverParams and this is specified, serverParams is used.	no	false

To enable the server, pass -Dorg.omegazero.proxy.serverImplNamespace=ntun.server as a command line argument.

To enable the client, either pass -Dorg.omegazero.proxy.clientImplNamespace=ntun.client as a command line argument or set alwaysEnableClient to true and set clientImplOverride on an UpstreamServer to ntun.client.
