DNS can be tricky.
on the 87U is VPN > Accept DNS Configuration set to ‘DISABLED’ as this then should just ignore DNS pushed by remote VPN server ? (if you older ASUSWRT-Merlin firmware version supports this option).
Just going through the basics, On your ASUS Router (VPN Server) is WAN DNS set to Quad9 and the LAN DNS to the Pi’s IP Address
i.e.
- Advanced Settings > WAN > WAN DNS Setting > ‘DNS set to Quad9’
- Advanced Settings > LAN > DHCP Server > ‘DNS set to Pi’s IP Address’
What DNS IP does the VPN clients end up using and are you using the guests wifi ?
I am thinking out loud but assume issue with rouge DNS has happened since introduction of Pi’s. maybe a idea to move the Pi’s to the ASUS’s DMZ.
This may make the architecture simpler especially and you main router (upstream) should still provide a proper firewall type service.
