If the checksum comes out as all 0's you're supposed to make it all 1's (0 in a UDP checksum means no checksum) so really it's related to that singular value and, if you've ever seen the quality of some of the dirt cheap hardware with ancient firmware some carriers use, it's really not that surprising for it to be bugged as described as they really don't care about dropping the occasional UDP packet when it's probably dropping more than that of general traffic due to how cheap and overrun it is anyways. |
