At factory defaults, your Opengear device's primary Network Interface (otherwise known as wan/eth0/NET1) has both a DHCP client enabled and static IP settings of: 192.168.0.1 / 255.255.255.0
The best guide to initial configuration is generally the Quick Start Guide included with your Opengear device, or available for download here. This article largely reproduces the quick start instructions.
Note: This article covers configuration via the web UI, to configure from the command line see this article.
1. Connect the Opengear device's primary Network Interface (usually labelled NET1) to your network.
Note: The Opengear device's secondary interface (otherwise known as ManagementLAN/lan/eth1/NET2) can connect to a secondary network, e.g. a segregated management LAN, or to the WAN via an external access device for broadband out-of-band (OoB). Alternatively, it can connect to same primary network asNET1 for redundancy.
2. The Opengear device is addressable at either of two addresses, its built-in address of 192.168.0.1 or the the address its on-by-default DHCP client accepts from a DHCP server on your network.
Continue by using a browser on the same network as the Opengear device's NET1 ports with an IP address in one of the Opengear device's network range (i.e. 192.168.0.x/24 or the range used by your DHCP server).
3. Enter https://192.168.0.1/ or https://[DHCP-supplied address]/ in the address bar and press Enter.
Note: The Opengear device ships with a self-signed SSL certification, click through the Untrusted connection errors.
4. Enter the default system username / password: root / default
5. Click System -> IP -> Network Interface.
6. Select a Configuration Method for the primary Network Interface, Static to assign settings manually or DHCP to use your network's DHCP server.
If DHCP, skip to the next step.
If Static, enter an IP Address and Subnet Mask for the primary interface.
To allow the Opengear device to initiate or respond to network connections via an external router, enter this as the Gateway. Note that per-interface Gateways are supported (policy based routing).
To allow the Opengear device to resolve DNS names, e.g. for resolving NTP servers by name, or if you plan to use DNS relay, enter Primary and optionally Secondary DNS server addresses.
7. If you experience packet loss or failure to negotiate link with e.g. an upstream switch port, you can try setting Media to a specific speed and duplex matching the upstream port. Otherwise leave this at Auto.
8. Click Apply to assign the new address immediately. To continue configuration, ensure you can reach the network of the new address and enter it in the address bar.
Your Opengear device's unique network hardware (MAC) addresses can be viewed in the web UI by clicking Status -> Support Report -> IP Configuration, from the CLI by running the ifconfig command, and on the decals on both on the Opengear device itself and the box it was supplied in.
MAC addresses start with Opengear's vendor ID of: 00:13:C6:xx:xx:xx
The primary network interface is denoted: eth0
By default, Opengear networking supports IPv4 only – see this article for details on enabling IPv6.
