10. Repeat the procedure for all Arctic’s if there is more than one.
11. Click “Lock keys” in order to prevent accidental erasing of the keys.
12. In this example, the “SSH listens on port” field is left as default value 22.
Note: If you wish to change the port where the SSH sever is listening the incoming connections, be
aware that you must also make respective changes to the M2M GW’s firewall. In addition, the new
SSH port will also be used for making SSH connections to the M2M GW in order to access M2M
GW’s command line interface.
Do not try to test the SSH-VPN peer before the Arctic is configured. The peer checking is done in
the similar manner as in L2TP-VPN; see Figure 65: VPN peer test for reference.
14. Configuring the Arctic
While configuring the Arctic via Configurator GUI, it is good to follow certain practices:
• After configuring a setup page, first click “Apply” and then “Commit” buttons.
• Give Arctic time to store the settings to non-volatile memory after pressing “Apply”
(approx. 5 seconds) and pressing “Commit” (approx. 10 seconds) button.
• Most of the changes become active only after the Arctic is rebooted, so reboot the Arctic
after committing all the changes.
The configuration shown in the pictures below is matching the example configuration at page 11,
chapter 7.1 Scenario 1, M2M GW connected with public IP address.
14.1. Configuring the Ethernet settings of the Arctic
