Here at the very eastern part of the San Francisco Bay Area, we have TCI, and they also offer an @Home cable modem service. My installation uses a Motorola CyberSURFR (yes, that's how it's spelled, and I nearly gagged when I saw the box). Despite an incredibly cheesy name, it works just fine attached to my FreeBSD machine, and aside from a few mysterious outages, I've been quite pleased with the service. A few thoughts: 1. Different cable modem networks use different ways of allocating IP addresses. TCI@Home in my area allocates static IP addresses (as apparently ComCast is doing in your area), but some other networks do DHCP or other methods. 2. No one I've ever spoken to at @Home knows anything about FreeBSD. It sounds like you know what you're doing with respect to network configuration, so this probably won't be a problem. 3. It seems like the script kiddies like to rattle the doors of @Home customers a lot. Make sure you've taken some reasonable precautions to secure whatever machine you directly attach to the cable modem network. (Well, you should do this no matter what you hook up to, but that goes double in this situation.) 4. Instead of IP aliasing with user mode PPP, you'll want natd. Hope this helps...
