The WAN zone has to have at least one physical interface connected to it. Thus, the
last remaining interface cannot be deleted.
Multi-WAN Settings
Use the "Physical Interfaces" settings to customize the settings of the available physi-
cal interfaces to set up multi-WAN for your gateprotect Firewall.
Navigate to "WAN > WAN Zone > Physical Interfaces" to add a new physical interface
to the WAN zone or edit an existing one.
The "Physical Interface" settings allow you to configure the following elements:
Field Description
"Name" Displays the name of the WAN zone as specified under "WAN > WAN Zone" .
"Comment" Shows the comment as entered under "WAN > WAN Zone" .
"NAT" Displays the NAT settings as defined under "WAN > WAN Zone" .
"MTU Size" Set the maximum size of each packet (in bytes) for the WAN zone. The Maxi-
mum Transmission Unit can be any integer from 68 to 1500.
Note: To customize the "MTU Size" successfully, you need to disable the "Path
MTU Discovery" as it will overwrite the "MTU Size" , otherwise. Click the blue
link on the right of the input field to open "Firewall > System > Settings" and dis-
able "Path MTU Discovery" .
"Physical Interface" For newly added interfaces only: From the drop-down list, select a free network
interface (NIC) that is not currently associated with a zone.
"Mode" For edited interfaces only: From the drop-down list, select the mode used to
configure an IP address from the external network. The default setting is DHCP,
that is a public IP address is dynamically assigned to your gateprotect Firewall
by an upstream server. You can adjust the settings to one of the other values
as necessary (see below).
"MAC Address Override" Optional: Choose whether to use the default MAC address of your gateprotect
Firewall, or specify a different address.
If you change the "Mode" from DHCP to PPPoE or Static, additional settings become
available (see below).
Use the PPPoE mode to connect via Point-to-Point Protocol over Ethernet. PPPoE is
typically used to share a broadband connection, such as a single DSL line or cable
modem.
Field Description
"Username" Enter the user name required to connect to your Internet service provider.
"Password" Enter the password required to connect to your Internet service provider.
"Show Password" Optional: Select the checkbox to verify the password.
