CentOS 作为路由器--无法获取内部区域的静态 IP 地址

CentOS 作为路由器--无法获取内部区域的静态 IP 地址

我正在尝试使用 CentOS 7 盒子制作路由器。

enp2s2f0 ---> 外部区域 ---> 直接连接到互联网。 enp2s2f1 ---> 内部区域 ---> 连接到 PC(将来会连接到交换机)

查看我的实际 ifconfig 结果:

[root@localhost ~]# ifconfig
enp2s2f0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet 192.168.1.1  netmask 255.255.255.0  broadcast 192.168.1.255

我的接口配置文件:

enp2s2f0

HWADDR="00:16:35:5C:91:3A"
TYPE="Ethernet"
BOOTPROTO="dhcp"
ONBOOT="yes"
ZONE="external"

enp2s2f1

HWADDR="00:16:35:5C:91:39"
TYPE="Bridge"
BOOTPROTO="static"
ONBOOT="yes"
IPADDR="10.100.0.1"
NETMASK="255.255.255.0"
NM_CONTROLLED="no"

DHCPD 配置文件:

ddns-update-style interim;

allow booting;
allow bootp;
authoritative;

ignore client-updates;
set vendorclass = option vendor-class-identifier;


subnet 10.100.0.0 netmask 255.255.255.0 {
      interface                         enp2s2f1;
      range                             10.100.0.10 10.100.0.200;
      default-lease-time                21600;
      max-lease-time                    43200;
      option subnet-mask                255.255.255.0;
      option broadcast-address          10.100.0.255;
      option routers                    10.100.0.1;
      option domain-name-servers        8.8.8.8;
      next-server                       10.100.0.1;
}

防火墙规则:

[root@localhost dhcp]# firewall-cmd --list-all
internal (default, active)
  interfaces: enp2s2f1
  sources: 
  services: dhcpv6-client dns http https ipp-client mdns samba-client ssh
  ports: 
  masquerade: no
  forward-ports: 
  icmp-blocks: 
  rich rules:

当然,IPv4 转发也是启用的。

我的问题是,如果你查看 ifconfig 的结果,enp2s2f1 没有获得他的静态 IP,通常是 10.100.0.1

我删除了 NetworkManager。

内部电脑获取了 IP,但我无法 ping 通路由器,也无法访问互联网。

有任何想法吗 ???

谢谢

对于 enp2s2f1,更改:

TYPE="Bridge"

到:

TYPE="Ethernet"

除非您希望 enp2s2f1 成为网桥的一部分。如果是这样,请按照RHEL 7 说明
