Is there a step-by-step guide to the $SUBJECT ?
I would like to setup a system where the web and the
ftp server are behind a masqing/packet filtering machine.
So when the request arrives to the 80th port it's forwarded, let's say to
the 10.0.0.20 (the internal number of the webserver). And another
question: about ports. When a user starts an ftp connection it sends
packets to the port 21. But in some cases the files (packets) arrive at
some other unusual ports (eg. 5000 and so on). And if I deny the uses of
other ports than 20,21,25,110,443,80,22 they will never arrive. Or am I
wrong ? Thanks, and apologieses that I ask first not answers to questions.
I will do it later.
