Stream5 confusion
From: "Lay, James" <james.lay () wincofoods com>

Hey Team,

 

So...I'm doing my upgrade to 2.9.0.3, a perfect time to audit my .conf
files.  Maybe I'm over thinking, but I think I'm confused on the
reasons/differences for stream5 ports client/server/both.

 

The default config has things like:

 

                ports client 21 22 23 ...

                ports both 80 311 443 ...

 

Pretending that we don't have ftp, http, and telnet preprocessors,
wouldn't one want to put things like 21, 22, and 23 in as both or
server?  As I understand it, this is how it works, with port 80 as an
example:

 

                ports server 80, reassemble any local -> remote port 80

                ports client 80, reassemble local port 80 -> any remote
port

                ports both 80, reassemble local port 80 -> any remote
port or local port 80 -> any remote port

 

So why would one put port 21 in ports client since the chances of a
client port being 21 connecting to a remote server port 21 are slim to
nil?  Any hints would be most welcome...thank you.
