Can confirm this behaviour in Feisty. Only occurs on one of the Uni subnets I use, and only with Feisty (not Dapper or Edgy). Was fixed as per Bug #59331, or by installing Firestarter, presumably because Firestarter uses the iptables rule:
sudo iptables -t mangle -A FORWARD -p tcp --tcp-flags SYN,RST SYN -j TCPMSS --clamp-mss-to-pmtu -- cannot get an HTTP response from some sites https://bugs.launchpad.net/bugs/89160 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
