Hello Darin,
You may want to check the ePMP Elevate Quickguide here: https://support.cambiumnetworks.com/files/epmp-elevate/
ePMP Elevate does not support UBNT devices running in Router mode (http://community.cambiumnetworks.com/t5/ePMP-Elevate/Router-or-Bridge-Mode/m-p/63006#U63006). This could be related to some of the issues you are facing.
Regards
