In that case I'll take a wild stab. I'd guess that the traffic passing through the clamper is not TCP at that point -- it's either UDP or ESP, and therefore unaffected by TCP MSS clamping. Use IPTables to log the packets passing to your remote, and see what they are. I'm too lazy to reread your setup, but I suspect you'd need to originate the tunnel from Linux and not from XP in order to capture TCP. Can you drop the MTU in DUN somehow...? Peter E.
