4. MTU Tweaking FAQ MTU (Maximum Transmission Unit) will vary with connection type. Cable and non-PPPoE (Point to Point Protocol Over Ethernet) can use up to 1500. PPPoE connections (WinPoet, RASPPPOE, Enternet, etc.) can only use up to 1492. However, WinPoet and Enternet MTU must be set by hand in the registry. Others may use DRTCP to set MTU. Feedback received on this FAQ entry: BT recommend an MTU of 1492 for the VDSL2 (Infinity service). 2012-07-04 06:12:29 How does this relate to packet fragmentation? by Pinan edited by JMGullett last modified: 2007-02-21 16:07:46 The MTU setting controls the maximum ethernet packet size your PC will send (you did know the Internet works in packets, didn't you?). MTU and Windows and DefaultsUnless otherwise set, Windows defaults MTU to 1500, or a lower value of 576 for external networks. 1500 is OK unless you are running PPPoE, want to use IPSec (Secure VPNs) or both, then it's too big. 576 is not efficient for the broadband/Internet; it's too small.

How it works The problem affects a piece of software called OpenSSL, used for security on popular web servers. OpenSSL is an open-source project, meaning it was developed by really talented volunteers, free of charge, to help the internet community. Heartbleed exploits a built-in feature of OpenSSL called heartbeat. Heartbleed exploits a built-in feature of OpenSSL called heartbeat. The data that lives beyond this request "may contain data left behind from other parts of OpenSSL," according to CloudFlare. What should I do? If you need the TL;DR, here it is: do not panic.
