Local Networking Considerations

DHCP versus Static IP Addressing

If the site owner prefers not to use DHCP, you can set up the IQ Gateway to use a static IP
address. Use the Installer App to configure the static IP. Refer to
more information on the Enphase Installer App.
•
Tap the Network Connectivity menu item. This allows you to see if the IQ Gateway is using
DHCP or Static-IP, and it allows you to change this setting if needed.
•
Tap Check Network Connectivity to view the IQ Gateway connections.
WARNING: Do not change the IQ Gateway DHCP setting to use a static IP address
unless you also reserve the same IP address on the broadband router. See the
section on DHCP reservations in the router instructions. Failure to reserve the static
IP address on the router may result in duplicate IP addresses and intermittent
Internet connection problems with the IQ Gateway.

MAC Filtering

Check to see if MAC filtering is in use at the site. This has nothing to do with Apple Macintosh
computers, but rather, refers to the MAC (Media Access Control) address that each individual
network card possesses. The MAC Address is a 48-bit address, which uniquely identifies that piece
of hardware. MAC filtering is a security mechanism by which routers allow administrators to specify
which devices can use the router for access to the Internet. This prevents unauthorised/unknown
personnel from using the router to get to the Internet.
•
An example of a MAC address would be: 00:17:F2:D6:B1:45
•
MAC addresses contain six pairs of characters, including any number 0-9 and letters A-F.
•
The MAC address of the IQ Gateway will begin with:
If MAC filtering is in use at the site, identify the specific MAC address of the IQ Gateway and add it
to list of authorised devices on the router. The MAC addresses (wired and wireless) are located on a
label on the back of the IQ Gateway.

Firewall Settings

The IQ Gateway initiates outbound connections to Internet servers. Such connections may be
restricted by firewall rules set up on the site's broadband router. Broadband routers typically allow
all outbound connections but restrict any/all inbound connections. If outbound firewall rules are
applied at the site, you must configure a static IP address for the IQ Gateway and add new rules that
allow outbound access as follows:
Direction Source
OUT <IQ Gateway IP
address>
OUT <IQ Gateway IP
address>
OUT <IQ Gateway IP
address>
The IQ Gateway connects to these servers using their DNS names. If you add firewall rules for IQ
Gateway reporting, Enphase recommends using the DNS names rather than the underlying IP
addresses. This is because the IP addresses are subject to change without notice.
