About IPsec gateways

    Why am I unable to delete a VPN gateway?

    You can delete a VPN gateway only after you delete the VPN tunnel resources that are associated with the VPN gateway. For more information, see Deleting SSL VPN Gateways.

    What does a 50 Mbps bandwidth cap mean?

    A bandwidth cap for a VPN gateway is the maximum outbound bandwidth from the VPN gateway to the Internet.

    Why is the data upload speed only 2 Mbps while the gateway bandwidth is 50 Mbps?

    The data upload speed also varies based on your Internet access speed, in addition to the bandwidth specification that you purchased.

    Can I change an IPsec VPN gateway to an SSL VPN gateway?

    No, you cannot change the VPN gateway type.

    Does a VPN gateway support bandwidth configuration adjustment?

    Currently, you can adjust the bandwidth configuration only within some specifications, such as [20 Mbps, 100 Mbps] and [200 Mbps, 1000 Mbps]. For example, you can increase the bandwidth cap from 50 Mbps to 100 Mbps. If you want to increase the bandwidth cap from 100 Mbps to 200 Mbps, you must create a gateway that supports a bandwidth specification of 200 Mbps.

    Why does the monitoring data displayed on the VPN gateway and VPN tunnel sometimes differ?

    Currently, VPN gateway and VPN tunnel collect data at a different interval. The statistical granularity of the VPN gateway is 1 minute, and that of the VPN tunnel is 10 seconds. Therefore, the statistical data shown on the monitoring page of the VPN gateway may be different from that of the VPN tunnel.

    How does a VPN gateway work? How about its availability?

    A VPN gateway uses network functions virtualization (NFV) and an active-active hot backup mechanism. When one server fails, automatic switchover helps ensure the normal operation of your business.
    A VPN tunnel runs in the public network. Therefore, congestion, jitter, or delay in the public network may affect the VPN network. If your business is sensitive to delay and jitter, we recommend using the Direct Connect.

    How can I query the VPN gateway details?

    You can log in to the VPC console to query the VPN gateway details as instructed in Viewing IPSec VPN Gateway.
