I want to use sockv5 with socketio client

Hello,
Im unable to open port on PC(SERVERB) cause of ISP rejects.

I have coded with Socket.io Client (ServerB). Its connecting to SocketIO Server(Server A).
I can open ports on Server A. I want to use sockv5 server on ServerA but with ServerB IP address,
IS there any ideas how can I do it ? 
Thanks
