As long as you have a DOCSIS compliant modem - there should be NO issue as
to the vendor/model.

The FAQ's in existence are from days long-gone when setting up your Linux
box on a Cable modem meant hours of excruciating enjoyment..  My RH 7 & 7.1
Installations went perfectly and were assigned (via DHCP) an address as soon
as the modem was setup.

As with any firewall - block everything initially and only open that which
you need to function.  Allow return traffic on ports > 1024 and for remote
access I'd highly recommend SSH.

M1/RR blocks 135,137,139 to protect the masses from improperly configured
Windows boxes.  You can ask them to allow this traffic through if you
require those ports - it shouldn't matter either way unless you have some
business need.

I get 173K downstream (basically T1 speeds with compression) and 300K
Upstream.  Performace can/will vary depending on congestion in your
"neighborhood."
