Forward SNMP requests over a SSH connection (e.g. for use with Observium or other monitoring tools).

	#!/bin/bash

	# This script will make a local SNMP server accessible on a remote system by
	# forwarding its UDP traffic over an SSH connection.

	# To do this, the following port forwardings are applied (in this order):
	# - local TCP port 42061 (arbitrary) to local UDP port 161 (SNMP)
	# - remote TCP port 42061 to local TCP port 42061 (via SSH connection)
	# - remote UDP port 42061 to remote TCP port 42061
