Local Networking Considerations
DHCP versus Static IP Addressing
If the site owner prefers not to use DHCP, you can set up the Envoy to use a static IP address. Use the
Installer Toolkit to configure the static IP. Refer to enphase.com/installer-toolkit/ for more information on the
Enphase Installer Toolkit.

WARNING: Do not change the Envoy 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 Envoy.
MAC Filtering
Check to see if Media Access Control (MAC) filtering is in use at the site. An example of a MAC address
would be: 00:17:F2:D6:B1:45

If MAC filtering is in use at the site, identify the specific MAC address of the Envoy and add it to list of
authorized devices on the router. The MAC addresses (wired and wireless) are located on a label on the
back of the Envoy.
Firewall Settings
The Envoy initiates outbound connections to Internet servers. Such connections may be restricted by
firewall rules se
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 Envoy and
add new rules that allow outbound access as follows:
Direction
Source
Protocol
Port
Destination
OUT
<Envoy IP address>
TCP
80, 443
reports.enphaseenergy.com
OUT
<Envoy IP address>
UDP
80
ping-udp.enphaseenergy.com
OUT
<Envoy IP address>
TCP
80, 443
home.enphaseenergy.com
The Envoy connects to these servers using their DNS names. If you add firewall rules for Envoy 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.
