why even use the router ? you should be able to use the openbsd box as your firewall without the router -----Original Message----- From: Christopher Nehren [mailto:apeiron () comcast net] Sent: Wednesday, April 09, 2003 9:40 PM To: security-basics () securityfocus com Subject: Hardware + Software Router + OpenBSD DHCP / NAT Currently I have a cable modem in my house which feeds into a router. This router distributes the modem connection via DHCP to a few machines on my home network. I have an old machine running OpenBSD, and I'd like to know what a good (I suppose "best" would open a flame war?) solution would be, in order to increase my home network security using the OpenBSD system. I'm thinking of something like this: (please excuse my pitiful attempt at ASCII art) cable modem | | | router with the OBSD's system set as the DMZ | | - first ethernet interface on the OBSD machine OpenBSD system running DHCP / NAT + PF - second ethernet interface on the OBSD machine | | hub / switch | | client A / client B / client C ... / client Z Would this work? Would it be more secure to have the modem go to the OBSD box, then to a router, and then route the connection to the machines on the network? My main (only) concern with this setup is the security of my home network. ------------------------------------------------------------------- Is SPAM over-loading your e-mail server, disk space or bandwidth?
