Traffic targeting port service-node-port on the service node connected to ethernet-link will be forwarded to port target-port on target-ip.
Both tcp and udp will be forwarded unless one of the -tcp or -udp flags are given in which case only that protocol will be forwarded.
The service-node that will perform the port forwarding is selected automatically based on the Ethernet link unless one is specified using the service-node argument.
source-port can be used to specify the source port from which service node forwards packets to the target. If not specified, a dynamically allocated port will be used.
