I have two ISP and five lans network. I want LAN1-LAN4 to internet over WAN1, but LAN5 to internet over WAN2. I set two default gw.

/ip route
add distance=1 gateway=X.X.X.X,y.y.y.y

but it is run random over wan1 or wan2

1) Mark Routing from first 4 subnets to a specific routing mark, in ip/firewall/mangle
2) Use desired gateway for that routing mark, in ip/routes

3) Do the same for 5th subnet, or just let the default route catch that.

Hello,

Will not this web site be helpful?

PREROUTING DONT MARK PACKETS

I have modified my rules and it seems to work. It is alright?
