what http/https/ftp/smts proxy/relay to use on a network firewall
i'm trying to replace an ISA server used as proxy for incoming
connections to a web and a mail server with a linux box.
The iptables part is clear, also squid as proxy for client web access...
but What can be used for layer 3 proxies for server publications?
http proxy should be able to:
termination https connections (use http to internal servers)
handle (s)ftp (maybe a separate component)
link translation (replace internal links from the https servers)
no chaching needed
smtp relay (or proxy) should be able to
deny smtp sessoins for unknown recipients
