GCLOUD_COMPUTE_FIREWALL-RULEGeneralEComGCLOUD_COMPUTE_FIREWALL-RULES_UPDATE(1)

NAME
       gcloud compute firewall-rules update - update a firewall	rule

SYNOPSIS
       gcloud	 compute    firewall-rules    update   NAME   [--allow [PROTO-
	      COL[:PORT[-PORT]],...]]		   [--description DESCRIPTION]
	      [--source-ranges [CIDR_RANGE,...]]     [--source-tags [TAG,...]]
	      [--target-tags [TAG,...]]	[GLOBAL-FLAG ...]

DESCRIPTION
       gcloud compute firewall-rules update is used to update  firewall	 rules
       that allow incoming traffic to a	network. Only arguments	passed in will
       be updated on the firewall rule.	Other  attributes  will	 remain	 unaf-
       fected.

POSITIONAL ARGUMENTS
       NAME
	 The name of the firewall rule to update.

FLAGS
       --allow [PROTOCOL[:PORT[-PORT]],...]
	 A list	of protocols and ports whose traffic will be allowed.

	 PROTOCOL  is  the IP protocol whose traffic will be allowed. PROTOCOL
	 can be	either the name	of a well-known	protocol (e.g.,	tcp  or	 icmp)
	 or  the  IP  protocol	number.	A list of IP protocols can be found at
	 http://www.iana.org/assignments/protocol-numbers/protocol-num-
	 bers.xhtml.

	 A port	or port	range can be specified after PROTOCOL to allow traffic
	 through specific ports. If no port or port range is  specified,  con-
	 nections  through  all	ranges are allowed. For	example, the following
	 will create a rule that allows	TCP traffic through port 80 and	allows
	 ICMP traffic:

	   $ gcloud compute firewall-rules update MY-RULE --allow tcp:80 icmp

	 TCP and UDP rules must	include	a port or port range.

	 Setting this will override the	current	values.

       --description DESCRIPTION
	 A  textual  description for the firewall rule.	Set to an empty	string
	 to clear existing.

       --source-ranges [CIDR_RANGE,...]
	 A list	of IP address blocks that are allowed to make inbound  connec-
	 tions	that  match the	firewall rule to the instances on the network.
	 The  IP  address  blocks  must	  be   specified   in	CIDR   format:
	 http://en.wikipedia.org/wiki/Classless_Inter-Domain_Routing.

	 Setting  this	will override the existing source ranges for the fire-
	 wall. The following will clear	the existing source ranges:  $	gcloud
	 compute firewall-rules	update MY-RULE --source-ranges

       --source-tags [TAG,...]
	 A  list  of instance tags indicating the set of instances on the net-
	 work which may	make network connections that match the	firewall rule.
	 If  omitted,  all  instances on the network can make connections that
	 match the rule.

	 Tags can be assigned to instances during instance creation.

	 Setting this will override the	existing source	tags for the firewall.
	 The  following	 will clear the	existing source	tags: $	gcloud compute
	 firewall-rules	update MY-RULE --source-tags

       --target-tags [TAG,...]
	 A list	of instance tags indicating the	set of instances on  the  net-
	 work  which  may make accept inbound connections that match the fire-
	 wall rule. If omitted,	all instances on the network can  receive  in-
	 bound connections that	match the rule.

	 Tags can be assigned to instances during instance creation.

	 Setting this will override the	existing target	tags for the firewall.
	 The following will clear the existing target tags:

	   $ gcloud compute firewall-rules update MY-RULE --target-tags

GLOBAL FLAGS
       Run $ gcloud help for a description of flags available to all commands.
