Open or close server ports

Open server ports for remote access

IMPORTANT: Making this application’s network ports public is a significant security risk. You are strongly advised to only allow access to those ports from trusted networks. If, for development purposes, you need to access from outside of a trusted network, please do not allow access to those ports via a public IP address. Instead, use a secure channel such as a VPN or an SSH tunnel. Follow these instructions to remotely connect safely and reliably.

By default, 1&1 cloud servers have some or all of their ports closed to secure them against external attacks. In some cases, ports needed for specific applications to operate properly are also left open by default.

If you need to access your server remotely using a different port, you must first open the necessary port(s) using the 1&1 Control Panel.

NOTE: For servers launched through the Bitnami Launchpad for 1&1, select the cloud server you wish to modify in the Bitnami Launchpad and click the “Manage in the 1&1 Console” button to access the 1&1 Control Panel.

Follow these steps:

  • Log in to the 1&1 Control Panel.
  • Navigate to the “Network -> Firewall Policies” section.
  • Click the “Create” button to create a new firewall policy.

    1&1 firewall configuration

  • In the resulting form, enter a name for the firewall policy.

  • Enter a new firewall rule specifying the protocol, port range and list of IP addresses allowed to connect to that port. You can also click the “Add Predefined Values” button and select from a list of commonly-used ports to have the values pre-filled for you. Repeat this step until all the necessary ports are recorded.

    1&1 firewall configuration

  • Click “Create” to save and create the new policy.

  • Once the new firewall policy has been created, select it in the list of policies.

  • In the firewall policy details section, click the “Assign” button.

    1&1 firewall configuration

  • In the resulting dialog, select the server(s) to which you wish to apply the new firewall policy by name.

    1&1 firewall configuration

  • Click “Save Changes” to apply the new firewall policy to the selected server(s).

Your new firewall policy comes into effect immediately without any need to restart the server.

Close server ports and deny remote access

NOTE: For servers launched through the Bitnami Launchpad for 1&1, select the cloud server you wish to modify in the Bitnami Launchpad and click the “Manage in the 1&1 Console” button to access the 1&1 Control Panel.

To close a server port and deny remote access on that port, follow these steps:

  • Log in to the 1&1 Control Panel.
  • Navigate to the “Infrastructure -> Servers” section.
  • Look through the list of servers until you find the server you wish to modify. Click the server name.
  • On the resulting server detail page, find the “Firewall Policies” section and note the name of the firewall policy in use.

    1&1 firewall configuration

  • Navigate to the “Network -> Firewall Policies” section.

  • Look through the list of policies until you find the firewall policy for the server. Select the policy by clicking it.

  • In the “Configuration” section, review the list of rules for open ports. Close a port by clicking the minus icon next to it to remove the corresponding firewall rule.
