Finally I found solution. My ISP uses Cgnat so I need vpn to use torrent. We can't do whole process with web ui we need little help of commands. It is simple. Follow me.
 
	First we need create a "Connection Policy". This proccess can be done on web ui.
 
	1) Go to web ui > Conneciton Policies > Click Add Policy > Give any name (something like ProtonVPN) > Tick only your vpn connection > Save it
 
	Now we need to know our policy name.
 
	2) Go to command line and type: 
 
show ip policy
	You will get policies config on your router. Look for your policy description that you created before (ProtonVPN). Here I share some of config part.
 
{
	"policy": {
		"Policy0": {
			"description": "ProtonVPN",
			"mark": "ffffaaa",
			"table4": 10,
			"route4": {
				"route": [
	Here our policy name is Policy0.
 
	Ok. Last step.
 
	3) Type that command:
 
torrent policy Policy0
	All done. Check your torrent client connection. Now your torrent client use vpn connection that you want.
