Hi all,

I have searched the archives but could really find the answer I was
looking for.

I have a Sparcstation 5 running Aurora Linux (Red Hat based). It has
110Mhz Sparc Processor and 64MB RAM. I would like to configure this as a
router forwarding *ALL* incoming traffic to my internal LAN (a Windows
box) and allowing all outbound traffic. I would also like to monitor
*ALL* traffic passing through it. It will need to provide NAT services too.

I have read the IP-Masquerading howto and had a look at a few other
howto's but there seem to be an awful lot of ways to do NAT and forward
traffic.

2 questions:
1. Do you think the box is up to it (specifications wise) or am I
wasting my time? (It's currently acting as a Web/DNS and FTP server for
mainly my use)
2. How would it be best to accomplish this in the easiest way possible.
(also with as little load as possible on my Sparcstation).

Thanks

David
