That is not a valid test. In order to lookup the translated address
associated with a connection, that connection needs to be translated
(i.e. with a rdr-to rule).
"forward to nat lookup" is not usually the best way to implement this
sort of proxy anyway - "forward to destination" with a divert-to rule is
normally preferred.

that's the textual representation of ENOENT, which is the error returned
by the DIOCNATLOOK ioctl if no state matches the requested port/address
combo. in this case it doesn't refer to an actual file.
