Is there any advantage to inserting a router between the cpu and the ADSL modem to act as a hardware firewall? What I am really wondering is if the modem provided by SBC has any firewall capabilities at all? If there is an advantage to another router, can I use just a normal cable/dsl router or do I need to use a cable/dsl router and firewall? Any brand and model suggestions?

do you use pppoe on your pc?
or do you have a public ip address on your pc?
if so then your modem is in bridge mode and is not doing any firewalling whatsoever... it is acting truely as a bridge and just converting the atm to ethernet.
router will provide you the firewall function. because it is doing nat its a firewall in a way right off the bat. but you will also have the ability to add more pcs in the future if you decide to expand your home netowrk.
plus routers for cable/dsl are very cheap these days. its very little cost to pick one up.

A hardware firewall is always better than software firewall.
I work for a teco and we sell and install Efficient Routers. I have a 5930 at my house and when I block the remote access and set my default firewall to minimum. I am fairly well locked down. Most brands of DSL Routers will have similar firewall setups. Check with DSLREPORTS.COM or their equivalent to test you IP security.

Instead of adding a router and keeping the modem, why not just buy an all in one ADSL modem/router? There are plenty on the market and don't cost all that much.
From the one unit, the connection is managed, and you can control all the security settings from there.
The Netgear DG835 is a good unit (from experience), and has dual firewall capabilities (NAT/SPI).
are you based in the US or UK? In the UK..ADSL modemds supplied by ISP's tend to be an RJ11 connection from the phone line to the modem, and then a usb connection to the PC, with no other connections.
Obviously your's may be completely different, but in my experience with ADSL it's typical to replace the modem with a modem/router unit.
