Last Updated:May 13, 2026

Modify the maximum number of concurrent SSL connections for a VPN Gateway instance.

Background information

Item

Description

Limits

Reducing the maximum concurrent SSL connections may interrupt active sessions if the number of connected clients exceeds the new limit. We recommend that you implement a reconnection mechanism in your backend applications.

Effective time

The new specification takes effect immediately but may require several minutes to propagate across the network.

Billing impact

Billing starts based on the new specification after you submit the order. See SSL-VPN billing.

Use cases

If your business requires a different number of client connections, modify the maximum concurrent SSL connections for the VPN Gateway instance.

Procedure

  1. Log on to the VPN Gateway console.

  2. In the top navigation bar, select the region of the VPN Gateway instance.

  3. On the VPN Gateway page, find the target VPN Gateway instance.

    • To increase the number of SSL connections, click Upgrade in the Maximum Concurrent SSL Connections column.

    • To decrease the number of SSL connections, click Downgrade in the Maximum Concurrent SSL Connections column.

  4. In the SSL-VPN Connections section, select a new number of SSL connections.

  5. In the Terms of Service section, read and select the terms of service. Then, click Buy Now and complete the payment.
