B. You use VPN and encounter serious performance problems.

C. You used a program to optimize MTU for performance reasons, and now you

have connectivity or performance problems.

If you suspect an MTU problem, try changing the MTU to 1400. If this does not

help, gradually reduce the MTU from the maximum value of 1500 until the

problem disappears.

The common MTU sizes and applications are listed in the table below.

MTU

Application

1500

Typical for connections that do not use PPPoE or VPN.

1492

Used in PPPoE environments.

1472

Maximum size to use for pinging. (Larger packets are

fragmented.)

1468

Used in some DHCP environments.

1436

Used in PPTP environments or with VPN.

Note

A wrong/improper MTU value may cause Internet communication problems. For

example, you may be unable to access certain Websites, frames within

Websites, secure login pages, FTP or POP servers.
