Dual WAN Failover

RouterOS Beginner Basics
1

Hi folks, I have been working in IT for over 20 years and have been a Cisco instructor in the past, however MikroTik OS is new to me.

I have read many post but non seem to match my needs.

I want to achieve the following.

MikroTik hEXs Router running on 192.168.123.4

Virgin Media Fibre Broadband is running on a router at address 192.168.123.3

BT Broadband ADSL Backup is running on a router at address 192.168.123.1

I want device to have the MikroTik router at 192.168.123.4 as their gateway address. Under normal circumstances Virgin Media ONLY with be used for WAN. In the event of a service failure potentially monitored by ping using Googles DNS servers I wish service to switch to the backup BT router. As this router also has a 4G backup we should then have triple redundancy,

Thanks in advance for any assistance in this.

Hi!

Did you see this one?

Quote from that thread:

"Putting it all together into three lines that you can cut and paste. Just change “192.168.1.1” to the ip of your primary gateway and “192.168.2.254” to the IP of your failover gateway:

/ip route
add distance=1 dst-address=8.8.4.4/32 gateway=192.168.1.1 scope=10
add check-gateway=ping distance=1 gateway=8.8.4.4
add distance=10 gateway=192.168.2.254"

you basically add a route for 0.0.0.0/0 with gateway 8.8.4.4 and a route for 8.8.4.4 via your primary link.

Does this help you?
