Just added a DMZ and can't access my plex server.

I've been running a FreeNAS Plex server on my local pfSense network (192.160.30.1) without any problems. All my local machines and Roku have worked just fine.

I just added a DMZ (192.168.31.1) to my pfSense router. My Plex Server is still on 192.168.30.xx but I've moved the Roku over to 192.168.31.xx.

Now the Roku can't find my Plex server. My computers on the 192.168.30.1 work just fine.

Can anyone give me any suggestions on how to get the Roku on 192.168.31.1 to see the Plex server on 192.168.30.1?

Thanks,
