Pepwave max br1 mini wifi as wan config

I have a pepwave max br1 mini and I am trying to connect it to a DVR via the LAN port and use the wifi as wan to connect to my wifi and send the data on the hdd to the server. I currently do this with cradlepoints under the wifi as wan and the br1 max. How I do it on the other devices is that I set the LAN of my cradlepoint or br1 max to (example) 10.100.10.100 and I set the lan port on the dvr as 10.100.10.101 to be on the network of the device. Then I set the wifi as wan to connect to my network via wifi and choose nat and it nats over the internal lan of that device. I am not able to do this on the mini. I tried to set it up the same way but it is not working. I went in to nat mappings on br1 max mini and set the inside interface mapping for the lan to nat outside to the wifi as wan interface. My computer cannot see my dvr to bring over the footage on the dvr. Is the config on the max mini different? Also I cannot IP Passthrough the connect to make it a bridge either. Can I get some assistance from someone in the community
