Problem

Suggested solution

Cannot establish a VPN tunnel
  • Check that ARM600 has a default gateway configured for the eth0 interface.
  • ARM600 needs a public, static IP address. Provided that ICMP ping is allowed in the firewalls, check that ARM600 can be pinged from the Internet.
  • Verify that the OpenVPN ciphers in ARM600 and in Arctic Wireless Gateway/ Controller are the same.
  • Check that the border firewall does not block the traffic and that there is a port forwarding to ARM600, if the public IP is associated to the border router. At least the VPN port must be open (UDP 1194 for first OpenVPN server instance).

Cannot connect to the Arctic device's Patrol
  • Check that the registration password has been copied to Arctic Wireless Gateway/ Controller.
  • Check that the Arctic Wireless Gateway’s/Controller’s hostname is the same as the OpenVPN peer name in ARM600.
  • Check that the port TCP 10000 is open in the border firewall.

Cannot ping the devices connected to Arctic devices
  • Verify the routing settings, both in ARM600’s VPN settings and in Arctic Wireless Gateways/Controllers.
  • Check that the ARM600’s firewall allows the ICMP ping in the forward table.
  • If the ping target is a PC, disable the firewall of the PC or allow ICMP messages.

SCADA server is unable to connect the field devices through ARM600
  • The SCADA needs to be aware of the routing; define a static route in SCADA so that the field devices’ IP address range is routed through ARM600.
  • If the SCADA is in a dedicated LAN subnet outside ARM600’s LAN subnet, define a static route in ARM600 so that it is aware of the SCADA LAN subnet.
  • Verify that Arctic Wireless Gateways/Controllers have a route in the VPN settings (OpenVPN > Routing and Addressing) so that they are able to send reply packets through the VPN tunnel. Usually, the default route can be used.
  • Check that the field devices connected to Arctic Wireless Gateways/Controllers are configured to use the Arctic as a default gateway.

Cannot access the asset management features
  • Check that the device firmware versions are correct.
    • Arctic device Ver.3.3.1 or later
    • ARM600 Ver.4.2.1 or later
