I have some Path-MTU discovery problems it seems; a few sites I deal with can only communicate with us if we use an MTU of 1492 (they''re on ADSL of course ...) and another (in Japan) only works for file transfers if we use an MTU of around 1425. Is there any way to tell Linux what the MTU should be on a per-destination basis? -- Michael T. Babcock CTO. FibreSpeed Ltd.
