.Os
.Sh NAME
.Nm mygate
.Nd default gateway
.Sh DESCRIPTION
The
.Nm mygate
file is read by
.Xr netstart 8
at system startup time.
.Pp
.Pa /etc/mygate ,
if it exists,
contains the address of the gateway host.
The gateway is added to the routing tables by the
.Xr route 8
utility.
If
.Pa /etc/mygate
does not exist, no default gateway is added to the routing tables.
The file may contain gateway addresses for both IPv4 and IPv6 networks
in dotted quad notation for v4
.Pq e.g. 192.0.2.1
or in colon notation for v6
.Pq e.g. 2001:db8::1 .
Each address must be specified on a separate line.
If more than one address of a specific family is found,
only the first is used \- all other addresses of that family are ignored.
.Pp
.Pa /etc/mygate
is processed after all interfaces have been configured.
If any
.Xr hostname.if 5
files contain
.Dq inet autoconf
directives,
IPv4 entries in
.Pa /etc/mygate
will be ignored.
If they contain
.Dq inet6 autoconf
directives,
IPv6 entries will be ignored.
.Pp
Additionally, arbitrary shell commands can be executed during processing
of this file, using
.Ar \&! Ns Ar command
directives similar to
.Xr hostname.if 5 .
This is useful for doing additional configuration after all interfaces
are configured by
.Xr netstart 8 .
.Pp
Empty lines and lines beginning with
.Sq #
are ignored.
