The Ethernet interfaces are configured using the WHMI.
- Log in to the ARM600 WHMI.
- On the left pane, under Network, click Network Configuration.
- Click the Network Interfaces icon.
The Network Interfaces pane opens.
- Click Edit interface eth1 and configure the eth1 parameters.
Note: It is recommended to configure the eth1 interface first if applicable, as the PC is usually connected to ARM600 via the eth0 interface (applies only to ARM600 hardware variants).
Note: Change the IP address and netmask according to the required setup. Either set the netmask or the prefix (number of bytes in netmask), not both.
Table 1. Eth1 settingsParameter | Value |
|---|
Device | eth1 |
BOOTPROTO | none |
IPADDR | <IP address> |
NETMASK 1 | <netmask> |
PREFIX 1 | <prefix> |
DEFROUTE | No |
IPV6_DEFROUTE | No |
- Click Save.
- Click Restart interface eth1.
- Click Edit interface eth0 and configure the eth0 parameters based on the information received from the Internet Service Provider or from the ICT department.
Note: As the public IP address of ARM600 is case dependent, it is not possible to define an example. If ARM600 is located in DMZ, the eth0 IP address can be a private IP address. In that case the specific ports are forwarded to ARM600 by the border router.
Table 2. Eth0 settingsParameter | Value |
|---|
Device | eth0 |
BOOTPROTO | none |
IPADDR | <IP address> |
NETMASK 2 | <netmask> |
PREFIX 2 | <prefix> |
GATEWAY | <gateway IP> |
DNS1, DNS2 | Set the DNS servers, if needed. |
DEFROUTE | Yes |
IPV6_DEFROUTE | Yes |
Note: The default route is usually set pointing to the router in the ARM600’s eth0 subnet. The Arctic devices usually connect from unknown (dynamic) IP addresses via the eth0 interface, which is by default the WAN interface in ARM600.
- Click Save.
- Click Restart interface eth0.
CAUTION: The IP address of the eth0 interface used for the current connection to ARM600 has now been changed. After the changes to the eth0 IP address have been applied, the browser is not able to connect to ARM600 using the address https:// 10.10.10.10:10000.
- Switch the Ethernet cable from the ARM600’s eth0 port to the eth1 port (applies only to ARM600 hardware variants).
At this point, there is usually no need for adding static routes. If the SCADA or other control entity is in a different subnet than the ARM600 LAN, define a static route to that subnet. Do not define static routes over dynamic VPN tunnels.
