Subject: FW: Proxy vs NAT
You will also find that a Proxy is more application aware. This means
that the proxy for a specific application allows deeper packet
inspection for specific application calls.
As an example, ftp proxy will provide ways to finely control GET and PUT
processing, or even login names, directory commands, tcp tuning, etc.
As another example, an HTTP proxy will provide a deeper inspection of
the HTTP application (version dependent) that allows granularity for
doing things with GET REQUESTS, MIME types, etc.

One advantage of a proxy that comes to mind is that TCP sessions are
made from the user to the proxy then from the proxy to the server. Just
like CBAC it could block DoS and sync attacks. NAT would just send it
through.

Subject: OT: Proxy vs NAT
Sorry for posting the OT but I am really looking forward to hear from
the experts.
What are advantages and disadvantages of Proxy over NAT? Otherwise do
you recommend using a Proxy server behind a firewall for some reason?
Thanks,
