None of our internal network has 'real' IP addresses -I can, however use our
proxies to browse anywhere on the net. Our firewall has the task of
prtecting only a limited number of servers that are connected to the
Internet (mail gateways fore xample and the proxies).
today I can use IPP from my desktop machine to print to an IPP printer on
the INternet using our proxy. If I were to move to a different port then I
would not be able to do this - most proxies only work with a defined set of
protocols on well-known ports (HTTP, FTP mainly)
