Extremely. Without a Firewall, connecting to the Internet is an
invitation to pain, these days. :/

I would strongly suggest using the 'firehol' tool to do this.
You can find the website on it at <http://firehol.sf.net/>, and it is
packaged in Debian unstable (and probably testing by now).

Since it is a simple shell script, you can also use the same package in
a Debian stable environment, or grab it from SourceForge.

While it will not design your firewall for you, it makes it trivial to
implement and understand the iptables system.

You seem to be doing fine. :)
