# Tutorial: Adjusting the Maximum Number of VPN Tunnels

## Overview

This tutorial will guide you through the steps to change the maximum number of active incoming VPN tunnels on your Access Server.

> **Important**
>
> Changing this value will restart the OpenVPN daemons, disconnecting all current VPN clients. They will need to reestablish their connections, which should happen automatically.

## Prerequisites

- An installed Access Server.
- Console access and the ability to get root access.

## Step 1: Change the maximum number of active incoming VPN tunnels

1. Connect to the console and get root privileges.
2. Switch to the scripts directory:

   ```
   cd /usr/local/openvpn_as/scripts/
   ```
3. Adjust the maximum number of VPN tunnels with this command:

   ```
   ./sacli --key "vpn.server.max_clients" --value <NUMBER> ConfigPut
   ./sacli start
   ```

   Replace **\<NUMBER\>** with the desired maximum number of connected VPN tunnels.

   - By default, this configuration key isn't present in Access Server, and the limit is assumed to be 2048.
   - You can set it to any valid number of your choice.
