The workarounds in the 3rd link are still needed today (at least with TomatoUSB Toastman builds). The reason is that there are conflicting situations (ISPs mainly); for example the workaround is correct for Comcast here in the states, but causes breakage when used with some ISPs in Australia. So it's not something that Toastman, at this point, feels comfortable committing.
