CIPAFilter uses a lot of open source for our basic functionality, such =
as firewall, routing, NAT, etc... We use Ubunto Linux for the OS.  We do =
use ClamAv, but not freeswan or squid. (We did use freeswan in the =
past). =20

However, our core features (such as the proxy, reporting, greylisting), =
are implemented with proprietary non-gpl software we developed.  We also =
use spamassassin and sendmail in conjunction with a proprietary milter =
we developed for our mail features and to implement some extensions to =
SPF, greylisting and some additional header analysis. =20

There's no download link, but of course our customers can request any =
GPL software from us that we distribute with our product.  In some cases =
third parties can also make requests from us, but you need to be in =
possession of the binaries and request a specific software package used =
in the product by name. (See GPLv3 6-b).

We're very careful about licensing, none of our proprietary software is =
linked with GPL binaries or libraries, and as a company we focus on the =
development of our proprietary software.  Linux is a platform for us, =
not an end to itself.  It does, however, make an excellent platform.

But all that being said, we also believe in being in compliance with the =
spirit of the GPL.  For example, if someone wants the source for a GPL =
package I've actually modified I'll be happy to provide it via email at =
no charge,  and I don't much care if they're a customer or not.  But =
you'd have to tell me what package you want the source for.

Welcome, the list have been quite of late.

I was looking at CIPAFiler ..  It appears that CIPAFilter uses some =20
GPL'ed open source projects, e..g FreeSwan, ClamAV, squid.  -- do you =20
have a link to download the source of CIPAFilter ?  I'm interested in =20
learning more about it.

Regards.
