It would also Which I read as "and if it (PMTUd) *is* used, it is probably hindering performance". If what you meant was "if it isn't used, you're stuck with 576, which hinders performance", that that is quite correct... > I imagine this'll all change though whenever IPv6 comes about since the min. > MTU size will be (approx.) 1200. As another poster stated, IPv6 requires > PMTU, so this could become a nasty little problem. That other poster was me too... Unless I'm confused... ;) Hopefully we'll get lucky and the clue level required to deploy IPv6 will be high enough that people will get the obvious stuff right. ;) -- Valdis Kletnieks Operating Systems Analyst Virginia Tech Attachment:
