Configure a Site-to-Site Virtual Private Network (VPN) Connection on an RV340 or RV345 Router

Objective

A Virtual Private Network (VPN) is the connection between the local network and a remote host through the Internet. The local and the remote hosts may be a computer, or another network whose settings have been synchronized to allow them to communicate. This is true on all types of VPN. It typically allows both networks to have access to the resources on both sides of the connection. A VPN connection is commonly utilized in connecting a second office to the main office, or allowing a remote worker to connect to the computer network of the office, even if he is not physically connected to the network infrastructure. Remote workers typically connect via a VPN software client like AnyConnect, Shrew Soft, GreenBow and many others.

This article aims to show you how to configure a site-to-site VPN connection between an RV340 and an RV345 Router. It will call the primary router the local router, and the secondary router will be called the remote router. Be sure to have remote or physical access to the secondary router.

LAN networks must be on different subnets (for example 192.168.1.x and 192.168.2.x) or on totally different networks (for example 192.168.1.x and 10.10.1.x). If both networks were on the same subnet, the routers would never try to send packets over the VPN.

Configure a VPN Connection

Local Router

Step 1. Log in to the web-based utility of the local router and choose VPN > Site-to-Site.

Note: In this example, an RV340 is used.

Step 2. Click the plus icon.

Step 3. Ensure that the Enable check box is checked. It is checked by default.

Step 4. Enter the name of the connection in the Connection Name field.

Note: In this example, the name is TestVPN1.

Step 5. Choose the security settings of the connection from the IPSec Profile drop-down list. The options will depend on the IPSec Profiles created. For instructions on how to create an IPSec Profile, click here.

Note: In this example, CiscoTestVPN is chosen.

Step 6. Choose the interface to be used by the local router. The options are:

WAN1 — This option will use the IP address of the Wide Area Network 1 (WAN1) interface of the local router for the VPN connection.
WAN2 — This option will use the IP address of the WAN2 interface of the local router for the VPN connection. WAN2 is not available in single-WAN routers.
USB1 — This option will use the IP address of the Universal Serial Bus 1 (USB1) interface of the local router for the VPN connection.
USB2 — This option will use the IP address of the USB2 interface of the local router for the VPN connection. USB2 is not available on single-USB routers.

Note: In this example, WAN1 is chosen.

Step 7. Choose the identifier of the WAN interface of the remote router. The options are:

Static IP — This option will let the local router use the static IP address of the remote router when establishing a VPN connection. If this option is chosen on the local router, the remote router should also be configured with the same option.
FQDN — This option will use the Fully Qualified Domain Name (FQDN) of the remote router when establishing the VPN connection.
Dynamic IP — This option will use the dynamic IP address of the remote router when establishing a VPN connection.

Note: Interface identifier on the remote router should be the same as the Interface identifier of the local router. In this example, Static IP is chosen.

Step 8. Enter the IP address of the WAN interface of the remote router.

Note: In this example, 124.123.122.123 is used.

Step 9. Click the radio button for the Internet Key Exchange (IKE) Authentication Method that you need. The options are:

Preshared Key — This option means that the connection will require a password in order to complete the connection. The preshared key should be the same on both ends of the VPN connection.
Certificate — This option means that the authentication method is using a certificate generated by the router instead of a password when connecting.

Note: In this example, Preshared Key is chosen.

Step 10. Enter the preshared key for the VPN connection in the Preshared Key field.

Step 11. (Optional) Uncheck the Minimum Preshared Key Complexity Enable check box if you want to use a simple password for the VPN connection. This is checked by default.

Step 12. (Optional) Check the Show plain text when edit Enable check box to display the preshared key in plain text. This is unchecked by default.

Step 13. Choose the identifier type of the local network from the Local Identifier Type drop-down list. The options are:

Local WAN IP — This option will identify the local network through the WAN IP of the interface.
IP Address — This option will identify the local network through the local IP address.
Local FQDN — This option will identify the local network through the FQDN, if it has one.
Local User FQDN — This option will identify the local network through the FQDN of the user, which can be his email address.

Note: In this example, IP Address is chosen.

Step 14. Enter the identifier of the local network in the Local Identifier field.

Note: In this example, 124.123.122.121 is entered.

Step 15. Choose the IP Address type that may be accessed by the VPN Client from the Local IP Type drop-down list. The options are:

Subnet — This option allows the remote side of the VPN to access the local hosts in the specified subnet.
IP Address — This option allows the remote side of the VPN to access the local host with the specified IP address.
Any — This option allows the remote side of the VPN to access any of the local hosts.

Note: In this example, Subnet is chosen.

Step 16. Enter the IP address of the network or host to be accessed by the VPN client in the IP Address field.

Note: In this example, the IP address is 10.10.10.1.

Step 17. Enter the Subnet Mask of the IP address in the Subnet Mask field.

Note: In this example, the subnet mask is 255.255.255.0.

Step 18. Choose the Remote Identifier Type from the drop-down list. The options are:

Remote WAN IP — This option will identify the remote network through the WAN IP of the interface.
Remote FQDN — This option will identify the remote network through the FQDN, if it has one.
Remote User FQDN — This option will identify the remote network through the FQDN of the user, which can be his email address.

Note: In this example, Remote WAN IP is chosen.

Step 19. Enter the WAN IP address of the remote router in the Remote Identifier field.

Note: In this example, the remote identifier is 124.123.122.123.

Step 20. Choose the network type that the local network needs access to from the Remote IP Type drop-down list. The options are:

Subnet — This option lets the local hosts access the resources on the remote host with the specified subnet.
Any — This option lets the local hosts access the resources on the remote host with any IP address.

Step 21. Enter the LAN IP address of the remote network in the IP Address field.

Note: In this example, the IP address is 192.168.2.1.

Step 22. Enter the subnet mask of the remote network in the Subnet Mask field.

Note: In this example, the subnet mask is 255.255.255.0.

Step 23. Click Apply.

Step 24. Click Save.

You should now have configured the VPN settings on the local router.
