ダッシュボードでもFWaaSの管理オプションは利用できます。
/etc/neutron/neutron.conf
ファイルにおいて FWaaS プラグインを有効化します。
service_plugins = firewall
[service_providers]
# ...
service_provider = FIREWALL:Iptables:neutron.agent.linux.iptables_firewall.OVSHybridIptablesFirewallDriver:default
[fwaas]
driver = neutron_fwaas.services.firewall.drivers.linux.iptables_fwaas.IptablesFwaasDriver
enabled = True
注釈
On Ubuntu, modify the [fwaas]
section in the
/etc/neutron/fwaas_driver.ini
file instead of
/etc/neutron/neutron.conf
.
Configure the FWaaS plugin for the L3 agent.
In the AGENT
section of l3_agent.ini
, make sure the FWaaS extension
is loaded:
[AGENT]
extensions = fwaas
Edit the FWaaS section in the /etc/neutron/neutron.conf
file to indicate
the agent version and driver:
[fwaas]
agent_version = v1
driver = iptables
enabled = True
conntrack_driver = conntrack
必要なテーブルをデータベースに作成します。
# neutron-db-manage --subproject neutron-fwaas upgrade head
Enable the firewall option in the local settings file (named
local_settings
on RHEL and CentOS, and
local_settings.py
on Ubuntu):
OPENSTACK_NEUTRON_NETWORK = {
# ...
'enable_firewall' = True,
# ...
}
注釈
By default, the enable_firewall
option value is
True
in the local settings file.
設定を適用するために``neutron-l3-agent`` と``neutron-server``を再起動します。
Create the firewall rules and create a policy that contains them. Then, create a firewall that applies the policy.
ファイアウォールのルールを作成します。
$ neutron firewall-rule-create --protocol {tcp,udp,icmp,any} \
--source-ip-address SOURCE_IP_ADDRESS \
--destination-ip-address DESTINATION_IP_ADDRESS \
--source-port SOURCE_PORT_RANGE --destination-port DEST_PORT_RANGE \
--action {allow,deny,reject}
The Networking client requires a protocol value. If the rule is protocol
agnostic, you can use the any
value.
注釈
When the source or destination IP address are not of the same IP version (for example, IPv6), the command returns an error.
ファイアウォールのポリシーを作成します。
$ neutron firewall-policy-create --firewall-rules \
"FIREWALL_RULE_IDS_OR_NAMES" myfirewallpolicy
Separate firewall rule IDs or names with spaces. The order in which you specify the rules is important.
次のように、任意のルールなしで、ファイアウォールポリシーを作成し、後でルールを追加することができます。
For more details, see Networking command-line client in the OpenStack Command-Line Interface Reference.
注釈
FWaaS always adds a default deny all
rule at the lowest precedence
of each policy. Consequently, a firewall policy with no rules blocks
all traffic by default.
Create a firewall:
$ neutron firewall-create FIREWALL_POLICY_UUID
注釈
The firewall remains in PENDING_CREATE state until you create a Networking router and attach an interface to it.
