How can I send requests to WARP+ from users who connect to the Ubuntu server with Softether?

I have an Ubuntu server and I use it as a softether vpn server. I recently installed WARP+ on it. After connecting to the server with softether vpn client, the user’s requests will go to WARP+ and be answered. But when WARP+ It turns on, I can no longer connect to my server.

Please guide me, how can I fix this problem.
