That does not directly answer my question whether you are using an Intel NIC or not. I can lookup the motherboard model Asus Q87M-E for you... and bingo, it is using an Intel NIC.

So, Intel NIC does IPv6 TCP checksum offload which breaks your connection.

Go to your network adapter settings, select Intel NIC, configure, and disable IPv6 TCP checksum offload and you are done.
