OK, confirmed it is a byte order issue (port 20480 = 80, port 47874 = 443).

We've purchased an nProbe license to use with ntopng and this is currently
not working. When ntopng is used by itself on a standard Linux interface,
this issue does not appear. When using nProbe to caputure netflows, the
byte ordering issue shows up. Tried this with Ubuntu and Debian
distributions and both have the same issue.

Is this the right mailing list to ask for support?
