At risk of stating the obvious, any link or connection starts at a port on your local host and ends on some port on remote hosts (or vice versa). That's what the two mean. Example from my node:
Code:
Proto Recv-Q Send-Q Local Address   Foreign Address         State      
tcp        0      0 10.1.1.1:43025  unix.com:http           ESTABLISHED

Disregarding the first three columns it states that there's an established connection from my node on my private net using port 43025 to unix.com's www port, used for exactly the actual session.

SIMPLEPROXY(1)						      General Commands Manual						    SIMPLEPROXY(1)

NAME
simpleproxy - Simple tcp socket proxy SYNOPSIS
simpleproxy [-7] [-v] [-V] [-d] [-i] -P <POP3 users file> -L [<local host>:]<local port> -R <remote host>:<remote port> -S <proxy host>:<proxy port> DESCRIPTION
The simpleproxy program acts as a simple tcp proxy. It opens listening socket on local machine and forwards any connection to the remote host. OPTIONS
simpleproxy accepts following options: -V Version information. -v Makes simpleproxy to write activity information to syslog or stderr. -7 Makes simpleproxy to strip 8th bit. -i Use this flag when starting simpleproxy from INETD. -d By default simpleproxy does not detach itself from control terminal and writes all messages to stderr. This option will detach it from terminal and make it write messages to syslog. -L [<local host>:]<local port> Local host and port name or number to bind for listening. Host name is optional. -R <remote host>:<remote port> Remote host and port name or number -P <POP3 users list> If specified, simpleproxy will load list of users from the <filename> (one per line). After this it will be forwarding POP3 ses- sions only if client trying to authenificate as this user. -S <proxy host>:<proxy port> HTTPS proxy server host and port name or number. -a <HTTP Auth User>:<HTTP Auth Password> Authenticate to the HTTPS proxy server with the given userid and password. This option performs BASIC HTTP authentication as spec- ified in RFC 2617. Used only in conjunction with -S. -t <trace file> If specified, simpleproxy will dump all data that passes through connection to the specified file. BUGS
Only tcp ports are supported. SEE ALSO
