WAN Port Settings

Advanced > Advanced Network > WAN Port Setup
The physical port settings for each WAN link can be defined here. If your ISP account defines the
WAN port speed or is associated with a MAC address, this information is required by the router to
ensure a smooth connection with the network.
The default MTU size supported by all ports is 1500. This is the largest packet size that can pass
through the interface without fragmentation. This size can be increased, however large packets can
introduce network lag and bring down the interface speed. Note that a 1500 byte size packet is the
largest allowed by the Ethernet protocol at the network layer.
The port speed can be sensed by the router when Auto is selected. With this option the optimal port
settings are determined by the router and network. The duplex (half or full) can be defined based on
the port support, as well as one of three port speeds: 10 Mbps, 100 Mbps and 1000 Mbps (i.e. 1 Gbps).
The default setting is 100 Mbps for all ports.
The default MAC address is defined during the manufacturing process for the interfaces, and can
uniquely identify this router. You can customize each WAN port's MAC address as needed, either by
letting the WAN port assume the current LAN host's MAC address or by entering a MAC address
manually.
