## 问题合计
### 一、无法ping通设备，或者无法正常的局域网连通，检查两台设备的路由表
```javascript
ip route
如果出现
192.168.5.0/24 dev zt6jy5fync  scope link
# 表示直接连接（scope link）表示直接认为这个网段就在本地接口上


将报错如下：
root@Princess:~# ping 192.168.5.1
PING 192.168.5.1 (192.168.5.1) 56(84) bytes of data.
From 192.168.192.240 icmp_seq=1 Destination Host Unreachable
From 192.168.192.240 icmp_seq=2 Destination Host Unreachable
From 192.168.192.240 icmp_seq=3 Destination Host Unreachable

使用指令删除
ip route del 192.168.5.0/24 dev zt6jy5fync

清空缓存
ip neigh flush dev zt6jy5fync

##删除指令
sudo ip route del 192.168.1.0/24 dev zt6jy5fync scope link

sudo ip route del 192.168.1.0/24 via 192.168.192.47 dev zt6jy5fync

```
### 二、无法正常访问http
查看防火墙是否配置完成
```bash
iptables -L -n -v
```
输出结果包含：
```bash
Chain FORWARD (policy ACCEPT 0 packets, 0 bytes)
 pkts bytes target     prot opt in     out     source               destination
    0     0 ACCEPT     all  --  ovs_bond0  *       0.0.0.0/0            0.0.0.0/0
    0     0 ACCEPT     all  --  *        ovs_bond0  0.0.0.0/0            0.0.0.0/0
