我正在尝试配置绑定以在外部网络广播我的域,但我的服务器没有监听外部 IP。
本地一切运行正常。
我的网络界面:
enp4s0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
inet INTERNAL_IP netmask 255.255.255.0 broadcast 192.168.55.255
inet6 INTERNAL_IP_V6 prefixlen 64 scopeid 0x20<link>
lo: flags=73<UP,LOOPBACK,RUNNING> mtu 65536
inet 127.0.0.1 netmask 255.0.0.0
inet6 ::1 prefixlen 128 scopeid 0x10<host>
loop txqueuelen 1000 (Local Loopback)
即使关闭了 iptables:
sudo iptables -L -n
Chain INPUT (policy DROP)
target prot opt source destination
ACCEPT all -- 0.0.0.0/0 0.0.0.0/0
Chain FORWARD (policy DROP)

Chain OUTPUT (policy ACCEPT)
target prot opt source destination

命名的.conf.选项:
options {

我究竟做错了什么?
提前感谢您的帮助,Slawek。
答案1
我在 ubuntu 22 上使用 bind9 测试了您的配置。它正在运行。我认为您的端口转发功能运行不佳。您应该为 tcp 和 udp 协议进行端口转发
答案2
关闭,暂时停止乐趣,没有时间。感谢您的关注,我知道我还需要检查什么。问候。
