  * `network_address` - The *network* address to use.  This is your Lixonet routing layer address: 172.xxx.0.0 (especially take note of the last two 0's: `0.0` -- it _MUST_ end with zeros corresponding to the network size)
  * `asn` - The BGP ASN to use.  We usually follow the format `4206969XXX` where _XXX_ is the last octet of your `address`, zero-padded (i.e. 008 or 212)
 
-#### Tinc options
- * `tinc_bind_address` - OPTIONAL: The address that Tinc should bind to to _listen_ for incoming WAN-sided connections (i.e. 10.0.0.1).  This is _not_ the tunnel IP.
- * `tinc_connect_to` - OPTIONAL: A comma-separated list of well-known/pre-defined hosts to connect to (i.e. `denco_mane_lixo`).  If not supplied, this is automatically set to all core routers that aren't yourself (`name`).

If not supplied, this is automatically set to all core routers that aren't yourself (`name`).  Use this if you have an `eth1` that you _don't_ want to use for binding tinc to, and would prefer to bind tinc to `eth0` instead.

 #### Network options
  * `global_prefix`: global network prefix: defaults to `16`.
  * `router_prefix`: router network prefix: defaults to `24`. If you change this you _SHOULD_ change `netmask` too.
