            Bug ID: 271715
           Summary: VNET jail won't start if using ip4=3D or ip6=3D syntax =
in
                    jail.conf file. Syntax is specified in `man jail`
           Product: Base System
           Version: 13.2-RELEASE
          Hardware: amd64
                OS: Any
            Status: New
          Severity: Affects Some People
          Priority: ---
         Component: misc
          Assignee: bugs@FreeBSD.org
          Reporter: justin@tocci.org

steps to reproduce:
Add ip4=3Dinherit; or ip6=3Ddisable; and possibly other combinations to
/etc/jail.conf file and then attempt to restart a jail.

result:
root@host:~ # service jail restart net
Stopping jails: net.
Starting jails: cannot start jail  "net":=20
ng0_net
jail: net: vnet jails cannot have IP address restrictions
.

expected result:
This syntax is specified in `man jail`. If it is obsolete, please remove th=
is
paragraph from jail(8):

 ip4     Control the availability of IPv4 addresses.  Possible values are
             =E2=80=9Cinherit=E2=80=9D to allow unrestricted access to all =
system addresses,
             =E2=80=9Cnew=E2=80=9D to restrict addresses via ip4.addr, and =
=E2=80=9Cdisable=E2=80=9D to stop
             the jail from using IPv4 entirely.  Setting the ip4.addr
             parameter implies a value of =E2=80=9Cnew=E2=80=9D.
