What do you mean "is count(ed?) incorrect(ly?)"? Who's counting it? I
guess you are talking about another software here.

What kind of attack are you experiencing?

To my experience, a normal DoS firewall to avoid flood is a must have in
production, otherwise it's quite easy to eat all the CPU of a server.

For the "counting" of your VPS traffic, well under Xen, we use the
normal byte counter in /proc, and it's working pretty well.
