Why would running a DSL with NAT not be secure? I have ipnat doing address translation for me to a 192.168 network with ipfw running on the gateway box. I believe that is decently secure. Is it not? Or were you saying that plugging computers into the ethernet ports of the DSL device directly? Now that would not be secure, unless each machine was a firewall box I suppose. With my system there is a DSL box with 5 ethernet ports. I use one which connects to one of the two ethernet cards in my FreeBSD box which is acting as a gateway with ipnat. I then have a second ethernet card go out to a 8 port hub which then allows me to connect 7 other computers with 192.168.1.* addresses. And each one is then behind the ipfw firewall in addition to having the 192.168 private addresses. I feel it is rather secure, although I have not really had someone audit the system. As I learn more about ipfw rules I will get into the guts a bit more. And maybe I will be able to get udp traffic to go through so I can watch quicktime streaming properly on my iMac... :) Brennan Stehling - web developer and sys admin projects: www.greasydaemon.com | www.onmilwaukee.com | www.sncalumni.com Microsoft: Will you get a macro virus today?

The only problem is, I'm not getting a dsl modem from my telco, so I have to purchase one elsewhere. The best one I can find is an internal 3com PCI adsl ATU. Does anyone know if this is supported under Freebsd 4.0-Stable? If not, will it be if I upgrade to current? > To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
