Enabling local network traffic on Ubuntu

My local network consists of an NSLU2 (Slug), a printer and my router. I have made the considered conclusion that it is not going to cause much of an attack vector. My work enforced iptables disagrees, but fiddling with iptables scares me. Luckily I have found ufw, which makes life just *so* much easier: sudo apt-get install ufw sudo ufw enable sudo ufw default deny sudo ufw allow 192.168.1.0/24 Hey presto, I can see my local network. Life is good.
