Select Enabled from the Client VPN server pull-down menu on the Security Appliance -> Configure -> Client VPN page. You can then configure the following options:
- Client VPN Subnet: The subnet that will be used for Client VPN connections. This should be a private subnet that is not in use anywhere else in your network. The MX will be the default gatway on this subnet and will route traffic to and from this subnet.
- DNS Nameservers: The servers VPN Clients will use to resolve DNS hostnames. You can choose from Google Public DNS, OpenDNS, or specifying custom DNS servers by IP address.
- WINS: If you want your VPN clients to use WINS to resolve NetBIOS names, select Specify WINS Servers from the drop-down and enter the IP addresses of the desired WINS servers.
- Secret: The shared secret that will be used to establish the Client VPN connection.
- Authentication: How VPN Clients will be authenticated.
- Systems Manager Sentry VPN Security: Configuration settings for whether devices enrolled in systems manager should receive a configuration to connect to the Client VPN.
Authentication:
The VPN uses both pre-shared key based authentication and user authentication. To set up the user authentication mechanism, you will need to select your authentication method.

- Name: Enter the user’s name
- Email: Enter the user’s email address
- Password: Enter a password for the user or select “Generate” to automatically generate a password
- Authorized: Select whether this user is authorized to use the Client VPN
In order to edit an existing user, click on the user under User Management section. To delete a user, click the X next to the user on the right side of the user list. When using Meraki hosted authentication, the user’s email address is the username that is used for authentication.
RADIUS:
Use this option to authenticate users on a RADIUS server. Click Add a RADIUSserver to configure the server(s) to use. You will need to enter the IP address of the RADIUS server, the port to be used for RADIUS communication, and the shared secret for the RADIUS server.

Use this option if you want to authenticate your users with Active Directory domain credentials. You will need to provide the following information:
- Short Domain: The short name of your Active Directory domain.
- Server IP: The IP address of an Active Directory server on the MX LAN.
- Domain Admin: The domain administrator account the MX should use to query the server.
- Password: Password for the domain administrator account.
For example, considering the following scenario: You wish to authenticate users in the domain test.company.com using an Active Directory server with IP 172.16.1.10. Users normally log into the domain using the format ‘test/username’ and you have created a domain administrator account with the username ‘vpnadmin’ and the password ‘vpnpassword’.
- The Short domain would be ‘test’.
- The Server IP would be 172.16.1.10
- The Domain admin would be ‘vpnadmin’
- The Password would be ‘vpnpassword’.
At this time, the MX does not support mapping group policies via Active Directory for users connecting through the Client VPN.
Systems Manager Sentry VPN Security:
When using Meraki cloud authentication, Systems Manager Sentry VPN security can be configured. If your Dashboard organization contains one or more MDM networks. Systems Manager Sentry VPN security allows for your devices enrolled in Systems Manager to receive the configuration to connect to the Client VPN through the Systems Manager profile on the device.

To enable Systems Manager Sentry VPN security, choose Enabled from the Client VPN server pulldown menu on the Security Appliance -> Configure -> Client VPN page. You can configure the following options:
- Install Scope: The install scope allows you to select a set of Systems Manager tags for a particular MDM network. Devices with these tags applied in a Systems Manager network will receive a configuration to connect to this network’s Client VPN server through their Systems Manager profile.
- Send All Traffic: Select whether all client traffic should be sent to the MX.
- Proxy: Whether a proxy should be used for this VPN connection. This can be set to automatic, manual, or disabled.
When using Systems Manager Sentry VPN security, the username and password used to connect to the client VPN are generated by the Meraki cloud. Usernames are generated based on a hash of unique identifier on the device and the username of that device. Passwords are randomly generated.

Meraki Vpn Connection Authentication Failed
Cisco Meraki Client VPN only establishes full-tunnel connections, which will direct all client traffic through the VPN to the configured MX. As such, any content filtering, firewall or traffic shaping rules will apply to the VPN client's outbound traffic.
For remote teleworkers or users whose traffic should not be restricted in the same manner, clients can be configured to use a split-tunnel connection to direct traffic through the VPN only if necessary:
This article includes instructions for configuring split tunnel client VPN on Windows and Mac OS X. For standard Client VPN configuration on Windows and Mac OS X, please refer to our Client VPN setup guide. The rest of this article assumes a VPN has already been setup in this manner.
Note: This configuration involves manually adding entries to a client's route table, and should only be followed by users with a thorough understanding of routing mechanisms.
Configuring Split Tunnel for Windows
First, modify the properties of the VPN connection to not be used as the default gateway for all traffic:
- Navigate to Control Panel > Network and Sharing Center > Change Adapter Settings
- Right click on the VPN connection, then choose Properties
- Select the Networking tab
- Select Internet Protocol Version 4 (TCP/IPv4) and click Properties
- Click Advanced
- Deselect the box for 'Use default gateway on remote network'
- Click OK to apply the changes to the interface
Next, add routes for the desired VPN subnets. This should be done with the VPN tunnel connected:
Meraki Router Vpn
- Open a command prompt (hold down the Windows key and press 'R')
- Type 'ipconfig /all' and hit Enter (Note: The name of the VPN will not be displayed unless you are connected to the VPN)
- Under the list of interfaces, find the Description for the VPN connection created earlier. This will be needed later.
- Run the below command replacing the relevant information between the <> markings:
Note: 'Destination subnet' refers to the local LAN subnet (in CIDR notation) on the appliance's site, not the Client VPN subnet specified in Dashboard.
Use the same command, replacing 'add' with 'delete' to remove the route.
Configuring Split Tunnel for OS X
First, disable full tunnel (all traffic over the VPN):
- Navigate to the specific VPN settings for OS X, located under System Preferences > Network.
- Click Advanced Settings
- Under 'Options' section, deselect “Send all traffic over VPN”
Add a new route to local routing table:
Meraki Vpn Client
- Connect to the Client VPN
- Open the Terminal Application; normally this is located in Applications > Utilities > Terminal
- Verify the PPP interface that is being used for the Client VPN, this can be done by typing “ifconfig”
- As a superuser, enter the following command, replacing the relevant information between the <> markings:
Note: 'Destination subnet' refers to the local LAN subnet on the appliance's site, not the Client VPN subnet specified in Dashboard.
Ex. 'route add -net 10.3.0.0 -netmask 255.255.240.0 -interface ppp0'
To verify that the route was added take a look at the routing table, the new subnet should now have an entry. The route table can be accessed by typing 'netstat -r':
The route table will have to be modified depending on what networks will be accessed over the Client VPN (e.g. more than one network behind the concentrator). The interface will also have to be modified if there is more than one VPN configured on the client.
Verify Connectivity
Now that the route is added, a trace route can be performed to verify the direction of the traffic. All internet traffic should head out the normal interface and all VPN traffic should head to the PPP interface.

Note: These steps will have to be entered each time the VPN is brought up, but they can be defined in a script to make the changes quickly when needed. The specific process for this will be highly dependent on the operating system, tools available, and administrator preferences.
