MRU / MTU online test website
« on: December 31, 2015, 03:57:04 AM »

This service at
    http://www.letmecheck.it/mtu-test.php
tests your MRU / MTU. A simple-to-use tool, this website just does what it says on the tin. This service is really useful in tracking down potential nagging MRU-related problems if you have changed service type, changed to a two-box system of separate modem and router, or to a different model of separate modem. (See http://aa.net.uk/kb-broadband-mtu.html for explanation.) It speaks IPv6 too, which I need. Shows a real commitment to quality in design there.

I needed to test whether I could now dare to use full 1500 byte MRU / MTU with my DLink DSL-320B-Z1 modems instead of the annoying restriction to MTU 1492 that you often get with separate modems and PPPoE. When I changed from BTW 20CN to 21CN, I was finally able to use 1500 byte MRU despite having a separate router and PPPoE modem.

I notice that the site has a whole lots of other networking tools, a bit of a Swiss Army knife. Very useful
