I've tested connection speed using iperf twice: 1)directly over internet (without vpn) and 2) over vpn.
1: Rx=58Mbps, Tx=72Mbps
2: Rx=2Mbps, Tx=3Mbps
I've set mtu to 1450 and the speed over vpn is better now: Rx=10Mbps, Tx=16Mbps; but I think it should be close to direct connetction speed. How can I find out the correct mtu value?
