Overview
There are now multiple ways to configure the network interfaces on the Arcules Gateway. Depending on where you are in the installation process, you can either configure the network interface at the gateway's console via keyboard, or via the web portal.
Multiple NIC Configurations
NOTE: Multiple NIC Configurations are only supported on the Rack Mount Hardware version of the Arcules Gateway. Micro and Small Form Factor Gateways only have one NIC. See Physical Gateway Specifications here.
The current supported configuration of this feature is for when the gateway connection to the main corporate network or VLAN requires one network connection, but the network or VLAN where the cameras are located is segregated and requires a separate network connection.
The configuration needs to be as follows:
NIC1 (Primary NIC) - Internet-facing Network
NIC2 (Secondary NIC) - Isolated Camera Network
⚠️ Warning: The gateway supports a single WAN interface. Only NIC1 may be configured with a default gateway. NIC2 must not have a default gateway address and must operate as LAN-only.
An example of this configuration is shown in the Recommended Network Architectures article, as Recommendation 1 (linked above).
Currently the Multiple NIC Configuration does NOT support the following use cases:
Load Balancing
Redundant Connections/Failover
Configuring the NIC at the Console
When you are configuring the NIC for the first time, or the gateway is marked as Offline in the web portal, you will need to perform the configuration at the gateway's console. This will require a monitor and USB keyboard.
Monitor Requirements:
Small Form Factor and Micro Form Factor Gateways
HDMI or DisplayPort (Depending on physical model of the gateway appliance)
Rack Mount Gateways
VGA
Configuration
By default, the gateway will come up as obtaining an IP Address via DHCP for all available NICs in the system. If this meets your standard for your network configurations in your infrastructure, no further configuration is needed.
Generally, if you use DHCP, it is recommended to place a DHCP Reservation on the IP Address for the gateway device, for consistency.
Example of Status Menu:
NIC1 (DHCP)
NIC2 (Static)
From this screen, you would hit the F2 key to enter the IP Configuration screen
Example of IP Configuration Menu:
Once on this screen, there are a few fields you can change:
Select NIC - Hit Enter or the ↓ (Down key) will give you a list of available network interfaces to select to configure.
Configure IPv4 - This option is where you define the source of the IP Address for the machine
Automatic (DHCP)
Manual (Static)
IP Address
DHCP - This shows as ###.###.###.###
Static - Enter your defined IP Address here
Network CIDR - Subnet Mask as defined in CIDR Notation
DHCP - This shows as ###.###.###.###/##
Static - Enter your CIDR Notated network here (i.e. if your IP Address is 196.168.0.50, with a subnet mask of 255.255.255.0, you would enter 192.168.0.0/24)
Default Gateway
DHCP - This shows as ###.###.###.###
Static - Enter your defined IP Address for your default gateway here
❗️Unsupported Configuration: If NIC2 is configured with a default gateway, the gateway appliance may become unreachable or fail to connect to Arcules Cloud. This configuration is not supported.
DNS Servers
DHCP - Leave this Empty
Static - Enter your DNS Servers' IP addresses here. You can use multiple servers with a comma separating them, but no spaces (i.e. 8.8.8.8,8.8.4.4,192.268.0.1)
Verify Connection - By default this is checked. This will verify the network settings are valid and are accepted before committing them.
Save - Commit these changes
Example - DHCP
Example - Static IP (no default gateway, no DNS servers)
Once complete, hit the F1 key to take you back to the main status screen. The IP Configuration shown here will cycle between the configured network interfaces in the system.
Configuring the NIC within the Arcules Web Portal
Once the gateway has been successfully added to the Web Portal, and the gateway is in an Online status, you are now able to perform configuration maintenance within the Web Portal.
Once you log in to the portal, you will need to go to the Devices Page
On this page you will need to click on the gateway you wish to perform maintenance on, and open the device's properties.
Here you will notice there is a Connection section, containing each network card in the gateway, and the current configuration.
To make changes to this, click on the name of the network card you wish to modify. In this example, we will edit ens34.
As configured for DHCP:
As configured for Static:
Within this dialog, you can change the IP Address Allocation to either DHCP or Static, as well as enter the IP Configuration information (if Static).
Once you hit the Save button, the network card's configuration is transmitted to the gateway to perform the change. You will receive status updates as this is applied, and if it was successful.
