Yes. Sorry.

Aha! That is interesting. So Multinet do not control the local port 
number when in active mode. Does that mean it also accepts connections 
from anywhere for passive connections? Or how do they authenticate?
IP address only?

Now I understand how you meant it. I'm thinking local machine all the 
time, and all connections will have different local ports then. What 
remote port is used is also a different domain.

TCP can listen for, and accept multiple connections on one port. telnet 
is a typical example of this, as well as http. So I was wondering if 
Multinet also did that, but apparently not then. Thanks.
