Is there any way to have > a single NIC respond to more than 1 MAC address? Other than virtual eth0:x with different ipv4 addresses, I don't think so Chris. And thats not overly secure I've been repeatedly told. Its also very easily detectable by the isp's who take a dim view of such in their TOS. But multiple machines is no problem if you are willing to setup a system like I have here: DSL-modem<->Wan port Linksys BEFSR41 Lan port<->eth0 in firewall<->iptables<->eth1 \ in firewall<->netgear 8 port switch port 1 netgear 8 port switch port 2<->this machine netgear 8 port switch port 3<->100' cat5 to woodshop machine And I still have 5 ports to expand the system with! The linksys BEFSR41 is running in gateway mode and does the PPPoE for me. It cost me about 80 bucks at the time I bought it over a year ago. My firewall is an elderly 500mhz K6-III running an older 2.4.21-ck kernel The Netgear switch was about 30 bucks a couple of months ago when I added the woodshop box. This box is a 1400mhz athlon I built about 4 years ago, running FC1 and 2.6.x kernels, and the woodshop box is an elderly 233mhz p2, running FC2 with all yum updates applied as of yesterday. I have repeatedly given my outside address I can read on the lynksys's internal page to others to scan me for vulnerabilities, and have gone to the web pages that specialize in that but my address is a null box to the rest of the world, no response from any port. None, nada, zip. I kind of like it that way. If the script kiddies can't detect it, they don't have a reason to muck with dead address's. :-) It also pretty well kills any chance I'd have to run a bittorrent client and help out at new release time, and thats a :( -- Cheers, Gene There are 4 boxes to be used in defense of liberty.
