Description

Add a firewall rule for an appliance type.

Arguments

• {appliance}

  Appliance type (e.g., "compute").

Parameters

• [action=string]

  The iptables 'action' this rule (e.g., ACCEPT, REJECT, DROP).

• [chain=string]

  The iptables 'chain' for this this rule (e.g., INPUT, OUTPUT, FORWARD).

• [network=string]

  The network for this rule. This is a named network (e.g., 'private') and must be one listed by the command 'rocks list network'. To have this firewall rule apply to all networks, specify the keyword 'all'.

• [output-network=string]

  The output network for this rule. This is a named network (e.g., 'private') and must be one listed by the command 'rocks list network'.

• [protocol=string]

  The protocol associated with the service. For example, "tcp" or "udp". To have this firewall rule apply to all protocols, specify the keyword 'all'.

• [rulename=string]

  The rule name for the rule to add. This is the handle by which the admin can remove or override the rule.

• [service=string]

  The service identifier, port number or port range. For example "www", 8080 or 0:1024. To have this firewall rule apply to all services, specify the keyword 'all'.

• [table=string]

  The table to add the rule to. Valid values are 'filter', 'nat', 'mangle', and 'raw'. If this parameter is not specified, it defaults to 'filter'

Examples

• stack add appliance firewall login network=private service="all" protocol="all" action="ACCEPT" chain="FORWARD"

  Accept all services and all protocols on the private network for the FORWARD chain. If 'eth0' is associated with the private network on a login appliance, then this will be translated as the following iptables rule: "-A FORWARD -i eth0 -j ACCEPT"

• stack add appliance firewall login network=all service="8649" protocol="udp" action="REJECT" chain="INPUT"

  Reject UDP packets with a destination port of 8649 on all networks for the INPUT chain. On login appliances, this will be translated into the following iptables rule: "-A INPUT -p udp --dport 8649 -j REJECT"
