Port Restrictions

Port Restrictions limits selected outbound or inbound port use according to the current firewall policy.

Where to find it: Sign in as root, open Server > Firewall, then choose Port Restrictions.

Available to: Root only.

What this page does

Use Port Restrictions for provider operations in the server scope. Read the current state first because actions here may affect several accounts or shared services.

Before you start

Security controls can also block legitimate traffic. Review evidence first, prefer monitor or narrow exceptions where available, and verify both the protection and the customer service after saving.

Why use it — and when not to

Use Port Restrictions to reduce a specific, evidenced risk. Avoid broad blocks, global disables, or permanent exceptions when a monitor mode or narrower rule can solve the same problem.

How to use it

1. Open Port Restrictions in the correct role and confirm the selected target.
2. Review the current values before editing them.
3. Change only the fields required for the task and read any confirmation carefully.
4. Wait for a final result, then test the affected service or resource.

Result and next check

A successful action updates the selected SHM resource and returns a final status. Read that status and verify the resulting service before treating the work as complete.
