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.
