4 WAN 故障转移 (DHCP) MIKROTIK RB750Gr3

Question

我正在尝试使用 Mikrotik 进行故障转移，但没有成功

我目前有一个路由器（LRT224），我想换成（RB750Gr3），我需要通过移动网络建立备用连接

使用单个 ISP 设置 RB750Gr3 很简单，但是，当我想配置具有四个 WAN 接口的故障转移时，挑战超出了我的知识和耐心

ACTUAL ROUTER: LRT224 Dual WAN Gigabit VPN Router

NEW ROUTER: RB750Gr3
ROUTEROS: 7.10.2

INTERFACES
ETH1-LAN 192.168.1.1/24, LOCAL NETWORK
ETH2-WANDHCP CLIENT, GET PRIVATE IP FROM ISP GATEWAY (FTTH) NAT
ETH3-WANDHCP CLIENT, GET PRIVATE IP FROM ISP GATEWAY (CABLEMODEM) NAT
ETH4-WANDHCP CLIENT, GET PRIVATE IP FROM ISP GATEWAY (LTE ROUTER) NAT
ETH5-WANDHCP CLIENT, GET PRIVATE IP FROM ISP GATEWAY (4G ROUTER) NAT

CONSIDERATIONS
ETH[1-5]-WAN LOCAL LINK ALWAY UP AND LOCAL NEIGHBOUR GATEWAY IP IS UP (192.168.X.1)

LOCAL DHCP SERVER
INTERFACE: ETH1-LAN
IP-POOL: 192.168.1.100 - 192.168.1.200

FAILOVER (NO LOAD BALANCER)
