Reference Guide 74. Layer-2 (LAN) Commands
74.2.9 network
This command allows selecting whether an interface is logically part of the LAN or part of the
WAN.
QoS and NAPT functions handle traffic routed from LAN interfaces to WAN interfaces; port
forwarding rules (static NAPT) work only on WAN interfaces; and the default firewall policy
prevents inbound packets from WAN interfaces unless solicited by an active connection.
