Create Internal Network with M5Loco?

[videoVIP 0]

My client has an IP-based camera system (AvyCon) on-site which they wish to access via laptop or cellphone while on-site. They do not want the cameras on the Internet. The cameras would only be accessed locally, when within (close) range. I have an M5Loco which I set up as a "SOHO Router" and plugged in to the NVR's LAN port. I can connect to the M5 via it's SSID, but cannot get to the NVR. Any suggestions are greatly appreciated.

This is what the set-up will look like. (Sorry, not a professional topology mapper...)
