I am switching to a business Internet service with Mediacom. Unfortunately, they want to bond each public IP with a mac address. This is less than desirable, but I don't have anyone in the area that can provide a better solution with the bandwidth I need. I spoke with a few people about setting up a firewall with three external interfaces-one per IP. It seems that might work, but I am partial to my IPcop firewall. The addresses will all be assigned via DHCP. I'm wondering if I could just create aliases on the red interface of IPCOP, and set different hardware addresses per sub interface. I haven't got it to work yet, and assume I have something wrong in my syntax. Is there a way to create the three interfaces this way? Maybe there is a better way to do this???
