Create firewall rules

Firewall rules control inbound traffic to your VMs. Each rule specifies a protocol, port, source, and action. Rules are added to a firewall group, which is then attached to one or more VMs.

Before you begin

  • An active IBEE Solutions organization
  • At least one firewall group (a default group is created automatically)

Add a rule

1

Open Firewalls

In the portal sidebar, click Firewalls under Network.

2

Select a firewall group

Click the firewall group you want to add rules to. The group detail page opens with the IPv4 tab active.

3

Add a new rule

Click + Add Rule. A new rule row appears with the following fields:

FieldDefaultOptions
ActionAcceptAccept, Drop
ProtocolTCPTCP, UDP, ICMP, Any
Port(empty)Port number, range (e.g. 8000-9000), or leave empty for all ports
SourceAnywhereAnywhere (0.0.0.0/0), Custom CIDR
4

Configure the rule

  1. Select the ActionAccept to allow traffic, Drop to block it.
  2. Choose a Protocol — TCP, UDP, ICMP, or Any.
  3. Enter a Port number or range. For common services, use the quick-pick buttons: SSH (22), HTTP (80), HTTPS (443), MySQL (3306), PostgreSQL (5432), DNS (53), or MS RDP (3389).
  4. Set the SourceAnywhere allows all IPs, or choose Custom and enter one or more CIDR blocks or IP addresses.
5

Save the rules

Click Save Changes to apply the updated rule set. Changes take effect immediately on all VMs attached to this firewall group.

IPv6 rules

Switch to the IPv6 tab to add rules for IPv6 traffic. The interface is identical to IPv4.

Edit or delete a rule

  • To edit, change any field in the rule row and click Save Changes.
  • To delete, click the delete icon on the rule row and save.

System-managed rules cannot be edited or deleted. They are marked in the rule list and ensure essential network connectivity.

Example: allow web traffic

To allow HTTP and HTTPS from anywhere:

ActionProtocolPortSource
AcceptTCP80Anywhere
AcceptTCP443Anywhere

Example: restrict SSH to an office IP

ActionProtocolPortSource
AcceptTCP22Custom: 203.0.113.0/24

Troubleshooting

Cannot edit a rule System-managed rules are read-only. You can only edit or delete rules you created.

Changes not taking effect Ensure you clicked Save Changes. Rule updates apply immediately to all attached VMs.

Custom source validation error Enter valid CIDR notation (e.g. 10.0.0.0/8) or a single IP address. At least one CIDR or IP is required when using Custom source.
