Question Feasible and secure network layout?


Hi everyone,

Basically I'm wondering if it is possible to set up a network like so:

Internet <----- D-Link 604 router <----- 2 clients + server


and still have the server act as a proxyserver/firewall/fileserver? i.e. all three computers connected to the router individually.

Thanks

um if all of the puters are individually connected, then there is no way that one of them can firewall the others... it has no control of the flow of data. If I were you I would run to your local small puter store, and get the oldest piece of (>=486) refurb garbage you can find, and put 2 PCI NIC's of different brands in it. Then install OpenBSD and configure it something like this:

http://www.openlysecure.org/openbsd/..._firewall.html

Once you have this invisible bridge in place behind the router, you're able to specifically stop everything but that which you want going to the server, and make the client computers much, much more difficult to detect.

HTH

Ben.

I'm going to agree with the above message. If all of your computers are connected to the router directly (big no-no) then one of them cannot act as a firewall. You should try what is in this article with OpenBSD instead of FreeBSD to set up an anti-spam antivirus gateway firewall. Google around, the answers are all close.
