How to establish a VPN connection
VPN connection
To establish a VPN connection between the
FactoryTalk Remote Access Manager
and the Runtime installed on the remote device:
- Access theFactoryTalk Remote Access Managerand select .
- Browse through the domain pane on the left, and select the device for which you would like to establish a serial connection.
- Above the right pane, select theVPNbutton.
- TheInteractive AccessTool opens up. SelectConnection.
- In theVPNtab, you can select:
- Connection Details: Read-only details on the VPN connection between Runtime and the device.
- VPN Traffic Details: Read-only details on sent and received traffic sorted by IP address.
- IP configuration: Select how you wish to get a virtual LAN IP assigned betweenVirtual LAN IP address is assigned by RuntimeandVirtual LAN IP address is manually assigned.
NOTE:
On Ubuntu 22 devices, the VPN connection does not run if the
UEFI Secure Boot
is enabled.The Runtime releases random IP addresses within a given range in its network and builds up an ARP cache. Each IP address released within the same network that is not associated to any MAC address will be assigned to the VPN virtual network adapter.
NOTE:
Link-local addresses might not be unique beyond their network segment.
If the automation network uses link-local addresses belonging to class 169.254.0.0/16, the VPN adapter assigns an IP address compatible with the network according to the specifications provided by the link-local protocol itself.
If the Runtime network exposes more IP addresses of different classes, a virtual interface will be assigned to multiple IP addresses, each compatible with its class.
To set an IP addresses interval:
- Access the Windows Runtime installed on the remote device.NOTE: See Windows Runtime installation and configuration to learn more about Runtime installation.
- Select theVPNconfiguration tab.
- Flag theVPNentry.
- ClickConfigure.
- TheVPN Static IP poolopens up. Enter one or more IP address ranges in the relatedFromandTofields. You can also enter the subnetMask.
NOTE:
The conflicts check related to newly generated IP addresses is not automatically carried out and therefore lays on the user.
