If it does not have some type of interface that lets you configure
the firewall, then it probably does not have one. My DSL modem has a
web interface that lets you connect/disconnect, and configure a few
other features, but it does not have a configurable firewall. It
only blocks the ports my ISO does not want me using. Incoming port
80 and port 25 connections for example. It used to block outgoing
port 25 connections before I convinced them that I needed it for
outgoing connections to my hosted mail server.
