|
|
Hi,
I have a gentoo box that is behind a PC setup as a SMOOTHWALL FIREWALL, then a LINKSYS ROUTER,
then of course my cable modem. Everything works just fine.
My questions:
Is this setup ok, for a secure system?
Do I have to consider setting up a firewall on the linux box itself?
I'm going to install Samba, to get to a Windows PC, via a HUB. Do I have to do anything as far as security is concerned?
I do intend having a web/ftp facility up and going in the future, on the linux box. Are there any easy tutorials on setup? _________________ Many thanks in advance.
I appreciate your help.

No, unless you fear an attack from your internal network or if you don't trust the other firewalls in front of your machine. _________________ If you see any violations to the Guidelines, please report it. |

It would be better to have the web/ftp setup between the Linksys and Smoothwall firewalls. That way if you intend to have public access to those servers and they would become compromised you would have a layer of protection between the server and the desktops. This page here might clear it up a bit. http://grc.com/nat/nat.htm

Another PC running Web/FTP Server between my Router and Smoothwall Firewall. Setup as DMZ PC on router.
Is the above correct? _________________ Many thanks in advance.

That is correct. The idea being that the web/ftp server cannot talk to directly to the desktops behind the Smoothwall firewall, unless you allow it.

Ok - another PC for Web/FTP
Q1. Can Gentoo be setup with the above, just with the required facilities?
Q2. Are there any resources out there that you know about, regarding the setup, and config. _________________ Many thanks in advance.
I appreciate your help.

SmoothWall I never used but try their documentation they have listed: http://www.smoothwall.org/docs/
Basically just check the documentation that comes with the respective packages.

I cannot afford to get another PC at moment, but I have an urgent need to have home WWW server, asap.
Given the setup I talk about above, what would need to be done to secure my workstation, which would be the public WWW server, as well as for work - dangerous I know - but only temporary.
What would I need to do? _________________ Many thanks in advance.
I appreciate your help.
