Update -
So I'm not sure what the root issue was, however I decided to upgrade to the latest version. My network is fairly simple so reconfiguring is not difficult at all. I created a memstick image and nuked the installation and started fresh. Worked right out of the box. I added a few tweaks, like not letting my router serve 192.168.0.1-254, I limited it to a handful of IPs, etc.
So, now I have a clean install thats working, and I have reinstalled my packages. Next step, once I have time, is to configure it for PPPoE and get my Zyxel into bridge mode. I've searched quite a bit on the topic, but if anyone has any experience with that particular dsl modem/router and pfsense, any suggestions would be great. Thanks!
