3.1.2 Other Internet Settings
RIP (Routing Information Protocol)
This function allows RIP to accept updates from this connection. Note that private routing
information is never sent to this connection.
DNS Settings
Optional. If your ISP doesn’t provide you with a DNS server address automatically through
DHCP, enter a DNS server IP address here.
MTU Settings
Optional. The Maximum Transmission Unit (MTU) is a parameter that determines the
largest packet size (in bytes) that the router will send to the WAN. If LAN devices send
larger packets, the router will break them into smaller packets. Ideally, you should set this to
match the MTU of the connection to your ISP. Typical values are 1500 bytes for an Ethernet
connection and 1492 bytes for a PPPoE connection. If the router's MTU is set too high,
packets will be fragmented downstream. If the router's MTU is set too low, the router will
fragment packets unnecessarily and in extreme cases may be unable to establish some
connections. In either case, network performance can suffer.
