Resolve Names from LAN IPs in Darkstat and BandwidthD?

[trentdk]

I would like to resolve the LAN IPs in packages like Darkstat and BandwidthD, but I'm not quite sure how to do this. In Darkstat, I get "(Unknown host)" and in BandwidthD I get "Configure DNS to reverse this IP".

Do I configure something in pfSense, or on my local DNS server (on a windows 2008 box)?

You need to point your DNS settings in pfSense to your internal DNS servers. (System > General)

All my internal IPs are given out by DHCP. Let me know if I'm on the right track: in pfSense, under the DHCP Server service, there is a Dynamic DNS field; is that what I should be using to try and get pfSense's DHCP to update my DNS server?
