FreeBSD - 监狱内没有互联网连接

我目前正在尝试在 FreeBSD 上设置服务器。我想根据 ezjails 创建监狱手册。我按照示例在监狱内安装 BIND，但我陷入了安装步骤 ( make -C /usr/ports/dns/bind99 install clean)。

起初我以为我遇到了 DNS 问题（不好/etc/resolv.conf），但看起来我在监狱内根本没有互联网。

在主机上：（8.8.178.110是www.freebsd.org）

root@varda:~ # nc -z -w 2 8.8.178.110 80
Connection to 8.8.178.110 80 port [tcp/http] succeeded!

监狱内：

root@dns:~ # nc -z -w 2 8.8.178.110 80; echo $?
1

知道发生了什么事吗？

root@varda:~ # ezjail-admin list
STA JID  IP              Hostname                       Root Directory
--- ---- --------------- ------------------------------ ------------------------
DR  2    192.168.4.1     www                            /home/jails/www
    2    lo1|127.0.1.1
DR  3    192.168.3.1     dns                            /home/jails/dns
    3    lo2|127.0.2.1

（www是另一个监狱，我也有同样的问题）

答案1

你需要resolv.conf在/path/to/jails/etc/resolv.conf

这这是我在开始之前实际放入监狱的完整列表。
