Need: To setup a torrent downloader which can be accessible remotely. Installed Transmission package which is accessible in my network.

Setup : I am using a Tp-Link router which for some weird reasons is not allowing port forwarding. To overcome this problem of port forwarding I have setup openvpn on a VPS(server) and set it up on Pi (client) successfully.

Problem: After setting up VPN successfully on port 9091.I added VPN IP in whitelist in transmission setting.json. I tried to access transmission using the VPN IP but its not loading where as it is still working on my local ip. I think my Ethernet traffic is not routing through my vpn(Tun0). I'm very new to linux so any help would be appreciated.

Edit:Just checked my IP using this command " /sbin/ifconfig eth0 | grep "inet addr" | awk -F: '{print $2}' | awk '{print $1}' " which is still showing my etho ip instead of my VPN IP.

Thank you.
