88User Manual v16.2.1 ─ 01
The current version allows you to activate either failover (see Chapter 3.4.4.3, "Failover
Settings", on page 82) or WAN load balancing, not both together.
Some services rely on your gateprotect Firewall being reachable under a specific IP
address. If you supplied the external IP address of a specific WAN interface to those
services, they might not work reliably or fail completely if your firewall uses WAN inter-
face groups for load balancing. gateprotect Firewall offers automatic management of
DynDNS services to handle this issue. When configuring DynDNS, specify the external
IP addresses of those interfaces which should be communicated to your DynDNS pro-
vider and the order in which they should be used. Should an interface fail, gateprotect
Firewall updates the DynDNS settings automatically. For more information, see Chap-
ter 3.4.4.2, "DynDNS Accounts", on page 80.
Interface Groups Overview
Navigate to "WAN > WAN Zone > Interface Groups" to display the list of WAN interface
groups that are currently defined on the system in the item list bar.
In the expanded view, the left column of the table displays the "Name" of the WAN
interface group. The buttons in the last column allow you to view and adjust the set-
tings for an existing interface group or delete a group from the system.
For further information, see Chapter 3.2, "Icons and Buttons", on page 21.
Interface Groups Settings
Under "WAN > WAN Zone > Interface Groups" , you can add or edit an existing WAN
interface group for load balancing.
The "Interface Group" settings allow you to configure the following elements:
Field Description
"Name" Enter a unique name for the WAN interface group.
"Weight" Specify how much of the internet traffic routed through the interface group
should be handled by the interface by entering a value from 1 to 256. The
higher the set value, the higher the percentage of the internet traffic being
routed through that interface will be. Setting the same value for all interfaces
results in equal traffic distribution across all interfaces.
"Interface" From the drop-down list, select the interfaces which should belong to the inter-
face group and click "Add" . You can edit or delete each single entry in the list
by clicking the appropriate button next to an entry.
The buttons at the bottom right of the editor panel depend on whether you add a new
WAN interface group or edit an existing group. For a newly configured WAN interface
group, click "Create" to add the group to the list of available interface groups or "Can-
cel" to reject the creation of the new group. To edit an existing interface group, click
"Save" to store the reconfigured group or "Reset" to discard your changes. You can
click "Close" to shut the editor panel as long as no changes have been made on it.
