${CONFIG_SEARCH_PATHS[@]/%//INTERFACE.conf}.
|
||||
It is to be readable by wg(8)'s \`setconf' sub-command, with the exception
|
||||
of the following additions to the [Interface] section, which are handled
|
||||
by $PROGRAM:
|
||||
|
||||
- Address: may be specified one or more times and contains one or more
|
||||
IP addresses (with an optional CIDR mask) to be set for the interface.
|
||||
- DNS: an optional DNS server to use while the device is up.
|
||||
- MTU: an optional MTU for the interface; if unspecified, auto-calculated.
|
||||
- Table: an optional routing table to which routes will be added; if
|
||||
unspecified or \`auto', the default table is used. If \`off', no routes
|
||||
are added.
|
||||
- PreUp, PostUp, PreDown, PostDown: script snippets which will be executed
|
||||
by bash(1) at the corresponding phases of the link, most commonly used
|
||||
to configure DNS. The string \`%i' is expanded to INTERFACE.
|
||||
- SaveConfig: if set to \`true', the configuration is saved from the current
|
||||
state of the interface upon shutdown.
|
||||
|
||||
See wg-quick(8) for more info and examples.
