创建网桥

添加到 /etc/network/interfaces

其中 enp4s0 来自上一个命令的输出 2: enp4s0: <BROADCAST,MULTICAST

1. auto vmbr1
   
2. iface vmbr1 inet static
   
3. address 192.168.48.1
   
4. netmask 255.255.255.0
   
5. bridge_ports none
   
6. bridge_stp off
   
7. bridge_fd 0
   
8. post-up echo 1 > /proc/sys/net/ipv4/ip_forward
   
9. post-up iptables -t nat -A POSTROUTING -s ‘192.168.48.0/24’ -o enp4s0 -j MASQUERADE
   
10. post-down iptables -t nat -D POSTROUTING -s ‘192.168.48.0/24’ -o enp4s0 -j MASQUERADE

复制代码

启动网桥

1. ifup vmr1
   
2. 
   
3. Waiting for vmbr1 to get ready (MAXWAIT is 2 seconds).
   
4. 
   
5. ip address show dev vmbr1
   
6. 
   
7. 3: vmbr1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UNKNOWN group default qlen 1000
   
8. link/ether 16:cf:7e:23:de:1e brd ff:ff:ff:ff:ff:ff
   
9. inet 192.168.48.1/24 brd 192.168.50.255 scope global vmbr1
   
10. valid_lft forever preferred_lft forever
    
11. inet6 fe80::14cf:7eff:fe23:de1e/64 scope link
    
12. valid_lft forever preferred_lft forever

安装 DHCP 服务器

1. apt update
   
2. apt install isc-dhcp-server

复制代码

编辑 /etc/default/isc-dhcp-server

1. INTERFACESv4="vmbr1"

复制代码

编辑 /etc/dhcp/dhcpd.conf

1. option domain-name-servers 8.8.8.8, 8.8.4.4;
   
2. default-lease-time 600;
   
3. max-lease-time 7200;
   
4. subnet 192.168.48.0 netmask 255.255.255.0 {
   
5.    range 192.168.48.100 192.168.48.199;
   
6.    option subnet-mask 255.255.255.0;
   
7.    option routers 192.168.48.1;
   
8.    option broadcast-address 192.168.48.255;
   
9. }
   
10. 
    
11. host host2 {
    
12.     hardware ethernet 00:00:00:00:00:02;
    
13.     fixed-address 192.168.48.2;
    
14.     infinite-is-reserved on;
    
15. }
    
16. host host3 {
    
17.     hardware ethernet 00:00:00:00:00:03;
    
18.     fixed-address 192.168.48.3;
    
19.     infinite-is-reserved on;
    
20. }
    
21. authoritative;

复制代码

启动 DHCP 服务器

1. systemctl start isc-dhcp-server

复制代码

查看 DHCP 服务状态

1. systemctl status isc-dhcp-server

复制代码

sdqu

apt-get install isc-dhcp-server

mark一下

麻烦楼主安排一下小鸡自动获取 /128的 ipv6

母鸡有ipv6，小鸡好像可以自动获取 ipv6？

mmcloud

弄个小鸡，装个ros更方便。

没试过但想问：

不知道，等个大佬说一说

没试过但想问：

Proxmox 直接弄个ikuai的小鸡会不会就代替网管和dhcp的功能了
