WAN MTU Setup

The MTU (maximum transmission unit) is the largest data packet a network

device transmits. The normal MTU value for most Ethernet networks is 1500

bytes, or 1492 bytes for PPPoE connections. For some ISPs, you might need to

change the MTU. This is rarely required, and should not be done unless you are

sure it is necessary for your ISP connection. When one network device

communicates across the Internet with another, the data packets travel through

many devices along the way. If a device in the data path has a smaller MTU

value than the other devices, the data packets have to be "fragmented" to

accommodate the device with the smallest MTU value.

The best MTU value is often just the factory default value. In some situations,

changing the MTU value fixes one problem but causes another. Leave the MTU

unchanged unless one of these situations occurs:

A. You have problems connecting to your ISP or other Internet service, and

either your ISP or our technical support suggests changing the MTU value.

Below Web-based applications might require an MTU change:
