Qnap Qfinder cannot find Nas

[Kalmiany]

Hi

I have pfsense setup on a computer which has a wan lan1, is a secure network, lan2 is where most of computers and IoT things live inducing the nas and lan3 which has a tp-link ap attached. I have setup vlans across two of the NICs lan2 and 3 and for devices' needing access to ever or rules have been put in place.

My question is why can I ping the nas on lan3 from any other network but I cannot ping it by name and qfinder cannot find the nas. My ping sessions were from a windows 10 and I done then from pfsense.

I am guessing the there is something not right with my dns settings. I have attached some pictures. Lan2 serves the nas and lans3 mobile.

Hope that is enough information please let me know if more is needed.

Thank you.
