Hi,
ICS on a M$ box does both....
NAT is network address translation, which is the function of converting yr
private internal address <192.168.0.1> to a public accessible address
<xxx.xxx.xxx.xxx>
Proxy on the other hand just routes yr request as doesn't perform any
NATing, it does however provide a speed enhancement if the sites are cached
on the proxy
try this site for all yr tech q's http://www.pcwebopaedia.com/
there def:
Proxy server
A server that sits between a client application, such as a Web browser, and
a real server. It intercepts all requests to the real server to see if it
can fulfill the requests itself. If not, it forwards the request to the real
server.
2 main purposes: 1. Improve Performance & 2. Filter Requests
NAT
Short for Network Address Translation, an Internet standard that enables a
local-area network (LAN) to use one set of IP addresses for internal traffic
and a second set of addresses for external traffic. A NAT box located where
the LAN meets the Internet makes all necessary IP address translations.
NAT serves two main purposes:
a.. Provides a type of firewall by hiding internal IP addresses
b.. Enables a company to use more internal IP addresses. Since they're
used internally only, there's no possibility of conflict with IP addresses
used by other companies and organizations.
c.. Allows a company to combine multiple ISDN connections into a single
Internet connection.
hope it helps
Ivan
