Question

Hi, we are trying to FTP to a device remotely using a RUT955 (RUT9_R_00.07.03).

We've setup a VPN hub in RMS and created a route directly to the device (195.0.0.82).

We are able to FTP but are experiencing slow transfer speed of around 300-500 Kbps. I did some speed tests on the RUT955 and we get around 8 Mbps in download and upload and I get around 50-70 ms when I ping the device.

Are additional settings to change to speed it up?

I've attached the troubleshoot file, tcpdump and a layout of the setup. I couldn't create a tcpdump in the troubleshoot page so I did it in CLI instead.

Hello,

Your testing setup might be incorrect, as, if the speed test was performed from the RUT955, it probably has tested between a different endpoint than the PC you connect from.

A more representative result of available speed and bandwidth would be to test using iperf3 between your end PC and RUT955 or FTP server.

You could try enabling Software flow offloading, in Network -> Firewall -> General settings, but it may not provide any improvement in your case.

Best regards,

Hi, thanks for the reply and suggestion.

Here is the result from iperf3 between my PC and RUT955.

iperf Done.

I didn't see any improvement with Software flow offloading enabled.
