How to make pfsense so that each subnet goes through a specific gateway?

Question

pfSense

Pfsense is up on the hypervisor. There are 3 subnets lan1 lan2 lan3 and three providers: wan1 wan2 wan3.
Tell me how to do it, so that each subnet would go to the Internet through a specific gateway?
For example, lan1 through wan1 and lan2 through wan2...
Now I have 3 gateways configured, 1 active, 2 pending, how can I make them work at the same time? And then I'll just allow the firewall to go where necessary ..
Thank you!

Answer 1

Because the provider's gateway was one, put different ip to check the performance and now they are all online.
And to drive LAN traffic through a specific gateway is a firewall-rules-advanced settings.
