We are moving into an office after too long a time working in my
basement Yeah!  I have an old compaq 486 dx4 25-75MHz machine that has
been a firewall for a long time and using diald to handle dialing into
my ISP.  The office will have a 1.5 max download and 300 something
upload ADSL line installed.  will the old compaq keep up?  How will I be
able to tell?  I would rather not create a bottle neck right off the bat
although I don't plan on it being mision crit. until the website is up.

specs: 

dx4 25 intel 
40 MB RAM
10Mb ethernet
no X at all
kernel 2.2.5-15
ipchains 
masq.

I have a couple of other machines I could put to the task including an
old gateway 486 running an 83 Mhz pentium overdrive, and a newer amd k6
-2(3?) 350.  I just have no idea of the processing power needed to keep
up.

In a security related question, I have 5 ip addresses that are part of
the package.  Should I put the mailserver and webserver out there on the
same network as the incoming ADSL line or put it behind the firewall and
use ipportfw or whatever it is to get to the boxes?

Any and all opinions/comments welcome.  We are a startup and can't
afford full time networking guy yet and I will be doing the admin stuff
until we can get some real funding.  I have been dinking with linux for
over two years but I am sure that I don't know more now than I didn't
know when I started and now that wwe are going to have a dedicated line
with a static IP I am am running more than a little scared about the
security issues.
