DNS does not work on the nodes

Gluon nodes will ignore the DNS server on the WAN port for everything except the mesh VPN, which can lead to confusion.

All normal services on the nodes exclusively use the DNS server on the mesh interface. This DNS server must be announced in router advertisements (using radvd or a similar software) from one or more central servers in meshes based on batman-adv. If your mesh does not have global IPv6 connectivity, you can setup your radvd not to announce a default route by setting the default lifetime to 0; in this case, the radvd is only used to announce the DNS server.
