Security Gateway Manual
SG-2100
11.1 Requirements
• This guide assumes the underlying interface is already present (e.g. physical port, VLAN, etc).
• The WAN configuration type and settings must be known before starting. For example, this might be an IP
address, subnet mask, and gateway value for static addresses or credentials for PPPoE.
11.2 Assign the Interface
• Navigate to
Interfaces > Assignments
Look at list of current assignments. If the interface in question is already assigned, there is nothing to do. Skip
ahead to the interface configuration.
• Pick an available interface in
Available network ports
If there are no available interfaces, then one may need to be setup in some other way (e.g. VLANs).
• Click
Add
The firewall will assign the next available OPT interface number corresponding to the internal interface designation.
For example, if there are no current OPT interfaces, the new interface will be
OPT1
. The next will be
OPT2
, and so
on.
Note:
As this guide does not know what that number will be on a given configuration, it will refer to the interface
generically as
OPTx
.
The newly assigned interface will have its own entry under the
Interfaces
menu and elsewhere in the GUI.
11.3 Interface Configuration
The new interface must be enabled and configured.
• Navigate to
Interfaces > OPTx
• Check
Enable interface
• Set custom name in the
Description
, e.g.
WAN2
• Set IP address and CIDR for static, or DHCP/PPPoE/etc.
See also:
• Create a Gateway if this is a static IP address WAN:
–
Click
Add a New Gateway
–
Configure the gateway as follows:
Default
Check if this new WAN should be the default gateway.
Gateway Name
Name it the same as the interface (e.g.
WAN2
), or a variation thereof.
