Failover with 4xWAN

RouterOS Beginner Basics
1

Hello from Germany,

sorry for my “easy”-Englisch, i try my best.

My Problem:

I have 4 LTE Router at home because your slow Copper Connection.
Each of this Router making NAT to my local network.
I connected all 4 Router in my Mikrotik 750GL to balance my Internet Traffic between the four connections.
Every Connection is free for 30Gb DL-Traffic, regulatet by the ISP. If these Volume has been reached, the LTE router disconnect the PPPOE connection.

What i need is, that in this case the Mikrotik dont send the Outgoing Internet Traffic to the Router which has reached his Limited.

I Hope you understand my Problem

Kind regards
Markus

this will solve part of your problem in an elegant way (failover)

for loadbalancing you have to search the wiki for a solution.

Thanks for your answer.

i tried to configure the Failover settings but it´s not working an i didnt find the mistake.
i have 4 Wan Uplinks

Mikrotik ETh1 → 192.168.1.0 to my local lan.
Eth2: 192.168.2.1 connected to the LTE Router (192.168.2.2)
Eth3: 192.168.3.1 connected to the LTE Router (192.168.3.2)
Eth4: 192.168.4.1 connected to the LTE Router (192.168.4.2)
Eth5: 192.168.5.1 connected to the LTE Router (192.168.5.2)

i configured the following Routing masks:

dest: 8.8.8.8 - Gateway : 192.168.2.1 scope 10
dest: 8.8.8.8 - Gateway : 192.168.3.1 scope 10
dest: 8.8.8.8 - Gateway : 192.168.4.1 scope 10
dest: 8.8.8.8 - Gateway : 192.168.5.1 scope 10

dest: 0.0.0.0 gateway 8.8.8.8 check gateway: ping

then i see:
0.0.0.0 - 8.8.8.8 recursively reachable throuch 192.168.2.1

If i disconnect the pppoe connection of the LTE Modem behind 192.168.2.2 the routing didngt change to the next hop which is connected to the internet..

please help
