Re: [suse-security] suse web and ftp standalone firewall help
I have done it very successfully. With my setup I am
using SuSE Firewall2 and Squid Proxy server. I currently
have it setup as a caching proxy and am planning to end
the caching and start using it as a plain pass through proxy.

I did not have to worry about NAT. DHCP is supposed to
be very easy to setup now (since the breakup of ATT and
@home). I previously had to setup the machine name to be
passed to their DHCP server. But this supposedly is not
necessary anymore.

The Firewall2 sample files should get you through its
setup very well. You do not need a heck of a lot setup
in there as I remember (other than most of the default
settings which shut most everything down). I am running
some services for external consumption so my settings are
different from what you are looking for.

Give it a try. I think you will find that it is a very
good, pleasant learning experience. I was able to do
most everything from the documents and did not have to
fall back to the list for help. But, you can always post
to the list. A better list than the security list would
be the plain SuSE English list. It has a great bunch of
guys on it. I am off that list now since I do not have
time to go through the vlume of mail it generates.

Good luck.
