Backup WAN

RouterOS General

Hi

Please i have 2 sources of internet

  1. 10.0.x.x------------->41.x.x.x---------->41.x.x.x--------> 4.2.2.2
  2. 192.168.x.x -------------172.16.x.x---------->197.211.x.x-------4.2.2.2

i wish to have a fail-over in case “a” cannot reach the INTERNET then it switches to “b” to get to the INTERNET

i have used netwatch using 4.2.2.2 as the watch ip however when it switches to “b” 4.2.2.2 replies and then it switches back to “a”

is there another way i can achieve this ?

Thank but not really what I was looking for

This is the system I have

However if ISP1 is having issues or downtime at their own end so far the gateway is replying it will not switch to the ISP2

Im thinking of a system where I can watch the internet on a particular interface and when Internet is not going through I switches to the backup and when ISP1 is up it switches back again

By the way where is fewi or normis

How about bonding the two interfaces or if you have two devices, use VRRP

First create 2 routes rules to force a remote host through a specific wan. You need to change Host1 and Host2 to a public host like 8.8.8.8 and 8.8.4.4 and GW1 and GW2 to your gateway of each wan connection

/ip route
add dst-address=Host1 gateway=GW1 scope=10

add dst-address=Host2 gateway=GW2 scope=10

And then add gateway with distance 1 and 2 for failover and switch in case is coming back

/ip route
add distance=1 gateway=Host1 check-gateway=ping
add distance=2 gateway=Host2 check-gateway=ping
