Remote WWAN over VLan

Installing and Using OpenWrt
1

I would like to deploy a device as a sort of remote WWAN module. I have a portable router I use for AV production work and often, we have to locate in an area without a wired or good wifi signal. I would like to be able to place an EAP1750 where the wifi is good, and route it back to the router over a Vlan, while still being able to access the LAN Ip of the unit for administration.

It's probably simple, but so am I...

Thanks in advance!

Can you show us the topology you're proposing? And what equipment (beyond the EAP1750) you'll be using? A digram would be really helpful.
