2.5 Configuring an OPT interface as an additional WAN
Note: The default configuration of the Netgate 3100 includes one assigned OPT port which is separate from the
switch. The switch ports may also be configured as additional discrete OPT ports, see Switch Overview for details.
This guide configures an OPT port as an additional WAN type interface. These interfaces connect to upstream networks
providing connectivity to the Internet or other remote destinations.

Configuring an additional WAN
• Requirements
• Assign the Interface
• Interface Configuration
• Outbound NAT
• Firewall Rules
• Gateway Groups
• DNS
• Setup Policy Routing
• Dynamic DNS
• VPN Considerations
• Testing
2.5.1 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.
2.5.2 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).
