- Frequently Asked Questions
- ==========================
- .. _faq-dns:
- 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.
