Configures a node as a gateway in a specified network, allowing it to relay traffic for other nodes. The gateway can also function as an internet gateway if specified.

Arguments:
NETWORK NAME:		The name of the network where the gateway will be created.
NODE ID:			The ID of the node to be configured as a gateway.
RELAYED NODES ID:	A comma-separated list of node IDs that will be relayed through this gateway.
