Mtu Configuration - D-Link DFL-1100 User Manual

MTU Configuration

To improve the performance of your Internet connection, you can adjust the maximum
transmission unit (MTU) of the packets that the N
external interface. Ideally, you want this MTU to be the same as the smallest MTU of all the
networks between the DFL-1100 and the Internet. If the packets the DFL-1100 sends are
larger, they get broken up or fragmented, which could slow down transmission speeds.
Trial and error is the only sure way of finding the optimal MTU, but there are some guidelines
that can help. For example, the MTU of many PPPoE connections is 1480, so if you connect
to the Internet via PPPoE, you might want to set the MTU size between 1400 and 1480. DSL
modems may also have small MTU sizes. Most Ethernet networks have an MTU of 1500.
Note: If you connect to your ISP using DHCP to obtain an IP address for the external
interface, you cannot set the MTU below 576 bytes due to DHCP communication
standards.
