Manage cloud firewall rules
For a cloud firewall, you can add new rules, change the existing rules, reorder as well as include, shut down и deregulate.
Add rule
After adding a deny rule on the cloud router, active sessions that match the rule will be terminated.
You can add up to 100 rules per traffic direction (policy) for a single cloud firewall.
Control panel
OpenStack CLI
- В control panels go to Cloud platform → Firewalls.
- Open the firewall page.
- Select the direction of traffic:
Incoming traffic
Outgoing traffic
-
Open the tab Incoming traffic.
-
Click Create a rule.
-
Select an action:
- Allow — Allow traffic;
- Deny — Deny traffic.
-
If templates with rules for incoming traffic, select the rule. The Protocol, Source, Source Port, Traffic Destination, and Destination Port fields will be filled in automatically. Proceed to step 14.
-
If there is no suitable template, add your own rule for incoming traffic.
-
Select a protocol: ICMP, TCP, UDP or All (Any).
-
Enter the traffic source (Source) — IP address, subnet, or all addresses (Any).
-
Enter the source port (Src. port) — a single port, a range of ports, or all ports (Any).
-
Enter the Destination — IP address, subnet, or Any. If you specify a subnet, the rule applies to all devices on the subnet.
-
Enter the destination port (Dst. port) — a single port, a range of ports, or all ports (Any).
Traffic to any TCP/UDP port blocked in Selectel by default, will be denied even if you specify that port in the rule.
-
Enter a name for the rule or leave the name created automatically.
-
Optional: enter a comment for the rule.
-
Click Add.
-
Open the tab Outgoing traffic.
-
Click Create a rule.
-
Select an action:
- Allow — Allow traffic;
- Deny — Deny traffic.
-
If templates with rules for outbound traffic, select the rule. The Protocol, Source, Source Port, Traffic Destination, and Destination Port fields will be filled in automatically. Proceed to step 14.
-
If there is no suitable template, add your own rule for outbound traffic.
-
Select a protocol: ICMP, TCP, UDP or All (Any).
-
Enter the traffic source (Source) — IP address, subnet, or All (Any). If you specify a subnet, the rule applies to all devices on the subnet.
-
Enter the source port (Src. port) — a single port, a range of ports, or all ports (Any).
-
Enter the traffic destination (Destination) — IP address, subnet, or Any.
-
Enter the destination port (Dst. port) — a single port, a range of ports, or all ports (Any).
Traffic to any TCP/UDP port blocked in Selectel by default, will be denied even if you specify that port in the rule.
-
Enter a name for the rule or leave the name created automatically.
-
Optional: enter a comment for the rule.
-
Click Add.
- Check the order of the rules, they are executed in order in the list — from top to bottom. If necessary, change the order by dragging and dropping the rules. After creating the firewall, you can reorder.

Create a rule:
openstack firewall group rule create \

[--destination-port <destination_port> | --no-destination-port]Specify:
-
<action>
— action:allow
— allow traffic;deny
— deny traffic;

<protocol>
— Protocol:icmp
— ICMP;tcp
— TCP;udp
— UDP;any
— all the protocols;
-
traffic source:
--source-ip-address <source_ip_address>
— IP address or subnet. If you specify a subnet and assign this rule to an outbound policy, the rule will apply to all devices on the subnet;--no-source-ip-address
— all addresses (Any);
-
source port:
--source-port <source_port>
— a single port or a range of ports;--no-source-port
— all ports (Any);

-
port of call:
--destination-port <destination_port>
— a single port or a range of ports;--no-destination-port
— all ports (Any).
Traffic to any TCP/UDP port blocked in Selectel by default, will be denied even if you specify that port in the rule.

-
Add a rule to the firewall policy:
openstack firewall group policy add rule \
[--insert-before <firewall_rule>] \
[--insert-after <firewall_rule>] \
<firewall_policy> \
<firewall_rule>Specify:
--insert-before <firewall_rule>
— ID or name of the rule before which the new rule will be added. The list can be viewed withopenstack firewall group rule list
;--insert-after <firewall_rule>
