time your PPPoE disconnects and re-connects it will revert back to MSS limit of 1400

 

(Max packet size of 1440) and needs to be entered after PPPoE connects again. This

 

function does not work before PPPoE connects.

 

*Referring to RFC879, the MSS value = MTU - 40, so by limiting the MSS value,

 

you will get limited MTU value.
