[LUNI] what's your preference for LIVECD firewall

[Trev Peterson]

For Comcast I've found that powering off the modem, waiting a couple
minutes and then powering it on with the firewall as the only computer
connected works.  If not call Comcast and ask them to fix it.  Do not
mention you run Linux as they look for any excuse not to support you.
Just say you must connect the firewall to the modem and will not connect
the computer to it for security purposes.  I've done this many times and
most of the time you do not need to call them (depends on modem model I
think).

If he is using the Death Star (AT&T) as his provider, he'll probably be getting a 2Wire 802.11x DSL modem/router from them, and that will have a software firewall set up by default. Just figured that I'd chime in and let you know in case you run into conflicts.
