I have just setup a nice shiney new USG + USW-24 + 2xUAP home network, running the latest version of the Unifi controller software - v5.5.20.
I have a number of different VLANs setup and dnsmasq running on a VM on my network. The USG has DHCP disabled as dnsmasq handles everything DHCP/DNS related.
I am trying to setup a remote user VPN on the USG so I can connect in on my phone or laptop and access my main data VLAN (.10).
I followed the online guides and have enabled the USG radius server, setup the Remote User VPN (L2TP), and can successfully connect and authenticate using my Android phone. From my phone I can access the .10 VLAN via direct IP addresses.
However I cannot access anything via my internal hostnames/aliases - e.g. my openHAB server is 192.168.10.103 but is also accessible via openhab.home. However when connecting via the L2TP VPN I cannot *see* these hostnames.
I have tried leaving the VPN "Name Server" config on the USG empty, tried specifying the dnsmasq server, but nothing seems to work. Also tried explicitly setting the dnsmasq server IP address in the client VPN config, but no difference.
I know the phone can access those servers, but I just can't figure out how to get it to use the dnsmasq DNS server.
Anyone got any tips or suggestions about what I am missing here?!
