Arthur Fragoso, thank you for reporting this and helping make Ubuntu better. Could you please test the latest upstream kernel available from the very top line at the top of the page (not the daily folder) following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags:
kernel-fixed-upstream
kernel-fixed-upstream-VERSION-NUMBER

where VERSION-NUMBER is the version number of the kernel you tested. For example:
kernel-fixed-upstream-3.16-rc6

This can be done by clicking on the yellow circle with a black pencil
icon next to the word Tags located at the bottom of the bug description.

If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-VERSION-NUMBER

Once testing of the upstream kernel is complete, please mark this bug's
Status as Confirmed. Please let us know your results. Thank you for your
understanding.

Title:
  Networking - Destination unreachable (Fragmentation needed)

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  A few years ago, I was using Fedora 16 and I was unable to do any HTTP POST at the place where I work. So I tried Ubuntu 12.04 (or 12.10, I'm not quite sure) and it worked perfectly.
  Recently I updated it to 14.04 and the same problem I had in Fedora came back.
  I'm not an expert in understanding these network packages, but I read that it could be that the network manager could had blocked the ICMP MTU dicovery package. I can check and if it is so I can ask him to unblock it, but I think that more people could also have this problem, so I wonder how it was working in the previous 12.04/12.10 version and if it should work the same in the new version.
  Or maybe it's a different problem, I only have this problem at the place where I work.
