I have the following setup:
1. Asus RT-N66u in Country 1 connected to a public IP address running OpenVPN Server
2. Asus RT-N66u in Country 2 connected to the provider router (NAT) running OpenVPN Client (tap device), configured to route all traffic through the tunnel
Both routers are running TomatoUSB Shibby v120. On both sites I have a QNAP NAS connected to the router.
The issue is if I sync the data between the two QNAP NAS's with Unison the network on the openvpn client side is getting extremely slow and my internet radio stops working. How can I limit the QNAP box traffic going through the OpenVPN tunnel ?
In QOS page at the client site I am always see the OpenVPN connection and that's it. So the entry for the ssh/scp connection from the QNAP box to the second QNAP box is useless.
How can I bring the client site of the OpenVPN tunnel to QOS before sending any traffic through the tunnel ?
