So that answered the IP differences. I don't like the answer, but it makes sense. As for the MAC addresses -- yeah, sorry, we 'spoof' the MAC on my NIC to be like the MAC of my old router. This is because AT&T / Comcast sucks balls and won't give out static IP addresses anymore, so I didn't want to have to deal with DNS changes for all my virtual hosts when I switched from a Linksys WiFi Router to using a linux box as router/dhcp/firewall/wifi/etc. I hear that on the 30th of this month, when the actual change from attbi to comcast occurs, I'll get re-assigned a new dynamic IP again (and so I'll stop spoofing at that point I suppose).
