Default Cheapest port blocking firewall?

I need a very simple firewall BOX which passes everything through but
blocks specific ranges of port numbers.

I need to block ports like 137-139 which are used for windoze
networking (so that an infected machine on the other side cannot
browse the internal network) and all the high ports e.g. everything
150-65535 and that will block most standard P2P software configs.

Most firewalls seem to offer a huge # of features.

There are some ethernet to wifi boxes which can do this (although the
Linksys ones have a very limited number of port number ranges) but I
need ethernet to ethernet i.e. LAN TO LAN.

Any suggestions much appreciated.

An old computer, a copy of Debian/Ubuntu server and two NIC's and about
an hour reading on iptables should do it :-)

Running an old computer to serve as a firewall is certainly not the
cheapest in terms of running costs.

Also, unless you are knowledgeable about both Linux and firewalls, it
is likely to be extremely time consuming to set up.

Its not that bad these days. AND it can become a useful desktop machine
as well.


But a two port Ethernet router will do the same job, but sometimes it
wont..the price you pay for simplicity is lack of flexibility.

"Running an old computer to serve as a firewall is certainly not the

I'm sure the question was 'cheapest' not 'cheapest running costs'.

"Also, unless you are knowledgeable about both Linux and firewalls, it
is likely to be extremely time consuming to set up."

But if you are not knowledgeable about firewalls in the first place,
should you be trying to set one up?

Find yourself another group to play 'net job's worth in. Plonk!

But the running costs are costs just the same.

Smoothwall is easy to set up on a redundant machine.

Simple enough to be installed by home users with no knowledge of Linux

Support a wide variety of network cards, modems and other hardware

Manage and configure the software using a web browser

Run efficiently on older, cheaper hardware

That "Java Jive" hasn't got a clue wtf he's talking about IMO.

Fine, but that wasn't mentioned in the posts I was replying to, and it
still doesn't answer the point about running costs.

At least my points were based on logic, not abuse. Why don't you and
R Johnson cohabit in my plonk folder? In fact why not get married
there? You seem eminently well suited, or at least thoroughly to
deserve each other.

PLONK!
