OpenVPN Site to Site

Hi, I've got a PFsense router and an OpenWRT router I'm trying to set up an OpenVPN site-to-site tunnel between. The The PFsense side was pretty straightforward to set up, but I'm not so sure about the OpenWRT side. It appears I have the two sides connected, but it doesn't seem there's any traffic flowing. WHat kind of logs and information would I need to debug this? Alternatively, is there a LuCi GUI for IPSec?
