Unified Services Router Figure 24: WAN2 configuration for 3G internet (part 2) User Manual 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 speeds: 10 Mbps, 100 Mbps and 1000 Mbps (i.e. 1 Gbps). The default setting is 100 Mbps for all ports. 44

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

The port speed can be sensed by the router when Auto is selected. With this option the
