Whether the L2 interface of USG firewalls can function as a WAN interface?

4

The L2 interface of USG firewalls can function as a WAN interface.
The WAN interface mentioned here refers to an interface connected to an external network, generally an optical fiber of a carrier. IP addresses cannot be directly configured for L2 interfaces. Therefore, you can use the VLANIF interface as the WAN interface (L3 interface).
The configuration is as follows:
1. Choose Network > Interface. Create a VLAN interface, and set parameters such as the IP address, mask, and gateway.2. Choose Network > Interface. Change the mode of the corresponding L2 interface to Access, and add the configured VLAN interface.
