PPPoE Client Support on a Subinterface
Firewall supports a PPPoE IPv4 client on a subinterface to connect to your ISP using
an 802.1Q VLAN tag.
The firewall supports a
PPPoE (Point-to-Point Protocol over Ethernet)
IPv4 client on a Layer 3 subinterface for when your ISP indicates that
PPPoE over 802.1Q VLAN is the way in which to connect to its internet services. The
firewall establishes a PPPoE connection to the ISP using an 802.1Q VLAN tag. The
PPPoE client that you configure on the subinterface learns its IPv4 address from the
ISP, along with other information such as the IP address of the server, DNS
information, and MTU.
You can configure a PPPOE client on either a physical interface or a subinterface,
but not both at the same time. Only one PPPoE subinterface is supported on a
physical interface. Before you begin configuring a PPPoE client, ask your ISP what
VLAN tag to use for your connection. You will enter that tag when you configure the
subinterface number and Tag. The following task assumes you have already configured
a Layer 3 Ethernet interface on the firewall with a security zone.
Configure a subinterface as a PPPoE client (termination point).
Select and highlight a Layer 3 Ethernet interface.
To the right of the
Interface Name
and dot,
enter the subinterface number, which is the VLAN tag number that your
ISP provided.
Enter the
Tag
, which is the VLAN tag number that
your ISP provided. The actual VLAN tag ID is read from this Tag
field.
Select the
Type
of address as
PPPoE
.
Select
General
and
Enable
the subinterface.
Enter the
Username
and
Password
for the authentication you will
choose.
Configure additional characteristics of the PPPoE subinterface, such as the
type of authentication, requesting a specific IPv4 address, and creating a
default route that points to the default gateway that the PPPoE server
provides.
