MTU Configuration
To improve the performance of your Internet connection, you can adjust the maximum
transmission unit (MTU) of the packets that the DFL-700 transmits from its external interface.
Ideally, you want this MTU to be the same as the smallest MTU of all the networks between
the DFL-700 and the Internet. If the packets the DFL-700 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 PPP connections is 576, so if you
connect to the Internet via PPPoE, you may want to set the MTU size to this value. 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.
