ZenWifi ET8 Guest Network Mesh

[mpsharp]

Trying to put all my IOT devices on my guest network and still run pihole on my regular. Everything seems to work fine from the router, but the IOT network will only appear on the mesh node for a few minutes, and then will no longer serve new addresses via DHCP. Yes, I've configured the guest for all mesh nodes. Switching that off then back on seems to make things work for a few minutes, but then new clients no longer get IP addresses. Did a hard reset on the node and that hasn't helped. Anyone else getting this to work consistently?

Oh, forgot to mention everything appears to work fine if I allow the guest network access to my intranet, but then what's the point?

@mpsharp, what firmware is being run on the main router and on the aimesh nodes?
How have you configured Pi-Hole on the main router? In the LAN DHCP Server DNS fields or in the WAN DNS fields?

Good questions: ASUS 3.0.0.4.388_25124 (No Merlin available yet, right?)
I'm aware of the trap of having the pi-hole server on my intranet and the guest network unable to reach it, but right now I'm just testing with standard Cloudflare DNS and still see the same problem. Once I can get everything working without pi-hole, then I'll go back and see if I can hack around that.

FWIW: I've tried both the LAN DHCP and WAN DNS fields. I have this fantasy belief that if I set them differently, the guest network will pick up the WAN settings and my local will get the DHCP settings, but still trying to get the non-pi-hole solution working.
