You have one ethernet interface on the mobo, which has two sockets. Only one socket can be used at a time. >(The reason I am asking is that I currently have a few of my work computers >hooked up together via an ethernet LAN, and it is sensitive material.

DSL <-> Router w/NAT & Firewall <-> house LAN One of the nice things about a NAT/filter-firewall is that there simply is no route from the outside internet to your computer unless you explicitly create one. If you feel the material is more sensative than you'd like to risk with a NAT based firewall, then you need something more serious (and $) than what you'd find at Best Buy. One example of what you could do (off the top of my head)... Set up a Mac running IPNetRouter (NAT, filter-based firewall) and IPNetSentry (rule-based firewall and packet monitor). Put TWO extra ethernet interfaces on it. Set up the routes and filters in IPNR so that things off one LAN can route to the internet but things off the 2nd LAN cannot. THEN when you DO want 'net access from the 2nd LAN, you can just load a different configuration into IPNR. OTOH, you could bulid two house LANs anyway and use a MIL-spec T-bar switch to connect one LAN or the other to the DSL/router. You can even get switches rated for gov-classified facilities - that include large "spark" gaps between the contacts so "tricks" can't be used to make the data jump. :) >2.

I don't recommend them. Use a real hub. - Dan. -- PCI-PowerMacs is sponsored by <http://lowendmac.com/> and...
