This is absolutetly the way to do it with ADSL. Using a modem in bridged mode minimizes the responsability of the modem/router which is a potentially unstable device. Let the stable Linux box do the work (routing+nat) and get the public IP. And firewall the Linux box itself with iptables. This is the most flexible and stable way to go.
