IPv4 Configuration Types
• 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.
Gateway IPv4
The IPv4 address of the gateway inside the same subnet.
Description
Optional text describing the purpose of the gateway.
– Click Add
– Ensure the new gateway is selected as the IPv4 Upstream Gateway
• Check Block private networks
This will block private network traffic on the interface, though if the firewall rules for this WAN are not permis-
sive, this may be unnecessary.
• Check Block bogon networks
This will traffic from bogus or unassigned networks on the interface, though if the firewall rules for this WAN
are not permissive, this may be unnecessary.
• Click Save
• Click Apply Changes
The presence of a selected gateway in the interface configuration causes the firewall to treat the interface as a WAN type
interface. This is manual for static configurations, as above, but is automatic for dynamic WANs (e.g. DHCP, PPPoE).
The firewall applies outbound NAT to traffic exiting WAN type interfaces but does not use WAN type interface networks
as a source for outbound NAT on other interfaces. Firewall rules on WAN type interfaces get reply-to added to ensure
traffic entering a WAN exits the same WAN, and traffic exiting the interface is nudged toward its gateway. The DNS
Resolver will not accept queries from clients on WAN type interfaces without manual ACL entries.
