3.7 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 sp eeds: 10
Mbps, 100 Mbps and 1000 Mbps (i.e. 1 Gbps). The default setting is 100 Mbps for all
ports.
