10.0.0.2 (and 10.0.1.3) are your DNS servers on WAN as well.
What the heck is your ISP doing there?
Thats not my ISP, thats me. For some reason, DNS dosen't get passed through to pfSense, so I set it as 10.0.1.3 (Primary server on the wan side) and 10.0.0.2 (old router that this modem setup replaced). Reverted it to just 10.0.1.3, with the option to have it overidden enabled.
Edit: Updated to latest snapshot (1.2-RC3 built on Mon Nov 26 14:47:57 EST 2007) and it now gets my ISP DNS servers on vr0, or it could have been the reboot I don't know, I was pressing disconnect/connect last time and not getting the ISP dns.
