I haven't set the MTU explicitly, but the objects that are being served are (intentionally) very small, so I never transmit any packets that are anywhere near 1280 octets. However I see that I occasionally receive incoming packets that exceed 1280 (HTTP requests with large amounts of header information). I will try to reduce the advertised TCP MSS to prevent PMTUD in the inbound direction from ever becoming an issue. These jumbo requests occur very seldom though, so I'll be very surprised if the lowered MSS will make a noticeable impact on the measured client loss. Thank you for your feedback!
