Super slow VPN using OpenVPN
Hi all. Just received my Gold a couple of days ago and loving it. I now have the Blue at my business and Gold at home for site to site VPN and everything is working well. However, the problem I am having is that whenever I use the OpenVPN app on my phone or ipad when I am outside, the download and upload internet speeds become extremely slow, ~5 mbps. The problem even occurs when I am home using my home internet. At home when my devices are connected using FIrewalla VPN Client, the internet speeds are as fast as they should. But as soon as the devices are connected using the OpenVPN app, the internet speeds become less than 6 mbps.
- The same problem occurs when I connect to the Blue or Gold using the OpenVPN.
- Is this a common problem with OpenVPN connecting to Firewalla? Thank you.

The Speed of OpenVPN depends on a few things
1. your upload speed on your internet. (when you are VPN home, you are doing a traffic turn around)
2. the VPN encryption speed. (which is around 120mbit on the gold)
3. If you have other stuff active on your network, that may consume CPU.

Is it possible to have the non-VPN traffic go outside the VPN tunnel for OpenVPN? I believe that's what's causing the significant drop in internet speed if I am connected via OpenVPN.
As I mentioned previously, the internet speed is fast if I connect the 2 Firewalla boxes using the VPN Client feature.

I think there is a misunderstanding. The VPN client feature in the Firewalla app is working well for me, connecting the 2 Firewalla boxes with great speeds. It is the the app OpenVPN that's causing the significant slow down of the internet speed if the device is connected using the OpenVPN app.

@Nelson, you said that when you're connect from your phone / iPad using OpenVPN , your internet speed is about 5 mbps right ?
So, let's say that you're connecting to your Firewalla gold at your home, and I don't know your ISP and internet link speed, but let's say that you have like me a link of 100mbps... and this link upload is 6 mbps (the upload link for home seems to be the 6 mbps even if you have 1Gbps download speed)... so if you're connected to this link, that means your Firewalla will have a bottleneck of 6 mbps max!
That said, you may consider also that 6 mbps upload link is shared with your home devices as well, and your phone/iPad will have the max download speed of 6 mbps max!
Hope this help !
