Not directly answering your question, but...

You may wish to investigate one of the small standalone firewall
distributions such as Smoothwall, IPCop, or m0n0wall (bsd-based).
They will all easily run in 128mb, and are easy to configure.
They are all easy to install. 

M0n0wall looks intriguing, I may give it a try here someday,... it runs
from non-writable media such as a CD and saves config on a floppy. It
can be run from a hard drive or a flash memory card of some sort too.
The obvious advantage is that if someone cracks the machine they can't
do any damage (to it, directly) because it's not writable.

And you really shouldn't be running web- or file-servers on your firewall,
the more stuff running on it the more opportunities you present for an
evil person/entity to crack it.

I'd suggest using one of the above then put another machine in a DMZ
to do web server duty (if it is supposed to be externally visible--
otherwise put it on another machine INSIDE the firewall on the "green"
(allegedly safe) network).

I'm running Smoothwall Express 2.0 on my old K6-2/500 machine with
128MB of memory and a 3 or 4 gig drive. It just runs and runs and runs
and doesn't come anywhere near using up all the memory. Before that
box became available I ran it on things similar to P90 or AMD K5, both
around 90-100 Mhz for several years with 64MB of ram and it ran just
fine on those machines too.
