VPN Gateway:Modify the configuration of a VPN gateway

Item

Description

Applicable scenario

You can upgrade a VPN gateway if you require higher specifications.

Upgrade

Upgrade limits

• If the bandwidth of your VPN gateway is smaller than or equal to 200 Mbit/s, you cannot upgrade the bandwidth to 500 Mbit/s or 1,000 Mbit/s. If the bandwidth of your VPN gateway is 500 Mbit/s, you can upgrade the bandwidth only to 1,000 Mbit/s.

  Note

  If you use a VPN gateway that supports dual-tunnel IPsec-VPN connections, you can contact your account manager to remove upgrade limits on bandwidth.

• Your services are not affected during the upgrade process.

Effective time

A VPN gateway upgrade takes effect immediately. The new specifications are valid until the subscription of the VPN gateway ends.

After you upgrade a VPN gateway, the upgrade may not take effect immediately due to the network latency. Wait a few minutes.

Impacts on billing

After you modify a VPN gateway and submit the order, the system bills the VPN gateway based on the new configuration. For more information, see Billing.

Scenarios

You can upgrade a VPN gateway based on your business requirements.

Applicable scenario

You can downgrade a VPN gateway if you require lower specifications.

Downgrade

• You can downgrade the bandwidth of a VPN gateway.

• You can disable IPsec-VPN and SSL-VPN for a VPN gateway.

• You can decrease the maximum number of concurrent SSL connections for a VPN gateway.

Downgrade limits

• If you want to disable IPsec-VPN for a VPN gateway, make sure that all IPsec-VPN connections created for the VPN gateway are deleted. For more information, see the Delete an IPsec-VPN connection section of the "Create and manage IPsec-VPN connections in dual-tunnel mode" topic.

• If you want to disable SSL-VPN for a VPN gateway, make sure that all SSL and IPsec servers associated with the VPN gateway are deleted. For more information, see the Delete an SSL server section of the "Create and manage an SSL server" topic and the Delete an IPsec server section of the "Create and manage IPsec servers" topic.

• If the bandwidth of your VPN gateway is 1,000 Mbit/s, you can downgrade the bandwidth only to 500 Mbit/s. If the bandwidth of your VPN gateway is 500 Mbit/s, you cannot downgrade the bandwidth.

  Note

  If you use a VPN gateway that supports dual-tunnel IPsec-VPN connections, you can contact your account manager to remove downgrade limits on bandwidth.

• If the transmitted traffic of a VPN gateway exceeds the maximum bandwidth during the bandwidth downgrade process, connections may be interrupted. Therefore, we recommend that you enable automatic reconnection for your services.

• If you decrease the maximum number of concurrent SSL connections for a VPN gateway and the number of existing clients connected to the VPN gateway exceeds the new limit, some connections may be interrupted. Therefore, we recommend that you enable automatic reconnection for your services.

Effective time

A VPN gateway downgrade takes effect immediately. The new specifications are valid until the subscription of the VPN gateway ends.

After you downgrade a VPN gateway, the downgrade immediately takes effect. However, you may need to wait a few minutes due to network latency.
