This is probably a FAQ 
Torch seems to want to show a connection between 2 IP’s, and the Rx and Tx for each
interface the connection is running on.
For example the tik upstream is on ether1 and I am on ether2 with
a private 192.168.1.2. ftp to rahul.net, doing a download to me from rahul.net, shows the Rx and
Tx properly for both ether1 and ether3, and it shows the Src and Dst IP’s correctly AS IPS, but considers one source and the other destination which is meaningless because it is a two way conversation shown on one line.
Can someone clarify the sense of this word usage please?
