    Not possible. The reason is, there is no such thing as 'upload' on the network layer. Means, the network only knows there is a connection, and when the connection terminates, the transfer bytes may determine whether the past was an upload or a download. You will have to manually select what content can go to these links

    Ok - thanks.  But each packet has an origin and destination IP address/port which is why I thought it might be possible.  Firewall gold must not be looking that deep.  I know that when I write network software, I can open and bind a port to an IP address and "WRITE" to that open socket so it is easily identifiable as an UPLOAD packet as opposed to "READING" from the socket.

    How do speed tests do this?  They are counting download and upload packets?  I guess they must be doing it internally as they write and read - obviously not at the socket level.

    Thanks again for the info.
