I have a ton of weird requests in my VM's nginx access log. They all look something like this:

10.0.2.2 - - [14/Feb/2013:17:20:29 -0600] "W\xA7\x1FI\xA0\xFE\xD6\x1B\xAD\xE8\xCF4\xFBM\xBF\x1B\x12~\xFF\xF2\xDFu\x85\x15\x05\xCEQY" 400 172 "-" "-"

Everything is function correctly (10.0.2.2 is my host) and requests I make myself look normal, but I have quite a few of these requests which makes me curious if there is something happening or if this is normal to have happen?

Something on 10.0.2.2 is making invalid HTTP requests. Does the host SNAT incoming connections (thereby masking the actual source)? – mgorven Feb 15 at 0:38
10.0.2.2 is a physical windows box (what i meant by host) which is catching the requests and routing them to a virtualbox ubuntu VM. – Nick Bisby Feb 15 at 3:37
