In cloudyr/googleComputeEngineR: R Interface with Google Compute Engine

gce_make_firewall_rule(
  name,
  protocol,
  ports,
  sourceRanges = NULL,
  sourceTags = NULL,
  project = gce_get_global_project()
)

`name`	Name of the firewall rule
`protocol`	Protocol such as `tcp, udp, icmp, esp, ah, sctp` or IP protocol number.
`ports`	Port numbers to open
`sourceRanges`	From where to accept connections. If `NULL` then will default to `0.0.0.0/0` (everywhere)
`sourceTags`	A list of instance tags this rule applies to. One or both of `sourceRanges` and `sourceTags` may be set.
`project`	The Google Cloud project

A global operation object

If both properties are set, an inbound connection is allowed if the range or the tag of the source matches the sourceRanges OR matches the sourceTags property; the connection does not need to match both properties.
