Define "reverse proxy".

A reverse proxy is either a proxy server that is installed in a server
network or a network equipment. Typically, reverse proxies are used in front
of Web servers. All connections coming from the Internet addressed to one of
the Web servers are routed through the proxy server, which may either deal
with the request itself or pass the request wholly or partially to the main
web servers.

A reverse proxy dispatches in-bound network traffic to a set of servers,
presenting a single interface to the caller. For example, a reverse proxy
could be used for load balancing a cluster of web servers. In contrast, a
forward proxy acts as a proxy for out-bound traffic. For example, an ISP may
use a proxy to forward HTTP traffic from its clients to external web servers
on the Internet; it may also cache the results to improve performance.

I know what it is. I wanted to make sure that this what you really had in
mind. People throw around mis-used terminology all the time,...I wanted to
make sure what you meant by it.

Yes, a single nic ISA can do that,...but very little else. Read the article
I gave in the last post.
Personally I would never wast my money and time with a single nic ISA,...pay
thousands of dolloar for a Corp Firewall Product just to throw away %60
percent of its abilities?,...not me.

But in direct answer to your question,...yes you can do that with a
singel-nic ISA.

The reason why you should have 2 nics in the box is the word "through". I
have found it useful to have multiple nics on the inside .... read a book
about what it can do for you!
