I woul use this script for failover http://wiki.mikrotik.com/wiki/Failover_Scripting

i need that all connection go to wan1 except  connection to site  google.com to go to wan2

if the wan1 down all traffic go to wan2 and after wan1 is ok return to original situation.

/ip firewall address-list
add address=google.com list=google.com
/ip route
add distance=1 gateway=172.16.10.1%Wan2 routing-mark=Google
add distance=2 gateway=192.168.1.254%Wan1 routing-mark=Google
/ip firewall mangle
add action=mark-routing chain=prerouting dst-address-list=google.com new-routing-mark=Google passthrough=no

Is there any reason you aren't just using that then?

Even more so the corrected version I already gave you.

Ooh, well, that isn't really a scripting issue then.

Try adding this:

Code: Select all

/ip firewall address-list
add address=google.com list=google.com
/ip route
add distance=1 gateway=172.16.10.1%Wan2 routing-mark=Google
add distance=2 gateway=192.168.1.254%Wan1 routing-mark=Google
/ip firewall mangle
add action=mark-routing chain=prerouting dst-address-list=google.com new-routing-mark=Google passthrough=no

That should make all traffic going to the google.com IP address go out of Wan2. If Wan2 is disable or its gateway unreachable, it should send it out of Wan1.
I guess you can modify the failover script to change the distance of the two google routes too if you want.
