Specific local IP, to use a specific WAN problem

RouterOS Beginner Basics
1

Hi everyone. I need to forward traffic created from a specific local ip, to be routed to a specific wan. I have a routerboard 750 with 2 wan, but the biggest problems are the tournament poker games that users play. They cannot enter a tournament. Is there any solution so i can choose some users to use only one WAN for internet? Thnx in advance

Yes, use policy routing. Mark their connections with a routing mark in firewall mangle, and then install routes for those routing marks.

Thank you for your quick answer, but can you please help me out on how to add these rules? i have wan1 192.168.2.1 and wan2 192.168.0.1 with local lan in the range 192.168.1.x. Lets say i would like ip 192.168.1.37 to use only wan1? Or better yet if there is any specific solution for poker tournaments on facebook

/ip firewall mangle
add chain=prerouting src-address=192.168.1.37 action=mark-routing new-routing-mark=to-wan1
/ip route
add dst-address=0.0.0.0/0 routing-mark=to-wan1 gateway=192.168.2.1

Or something like that.
