Title:
  Some HTTP connections are very slow or even time out

Status in “linux” package in Ubuntu:
  Expired

Bug description:
  After updating two machines to 12.04-beta1 I am experiencing problems with some websites.
  E.g. google.com has a very slow response, some sites, like http://myremotesetup.com, even time out.
  Executing this command seems to fix it:

  iptables -A FORWARD -p tcp --tcp-flags SYN,RST SYN -j TCPMSS --clamp-
  mss-to-pmtu

  This wasn't an issue before, i.e. with 11.10 and 11.04.

  
  ~# lsb_release -rd
  Description:    Ubuntu precise (development branch)
  Release:        12.04

  ~# apt-cache policy iptables
