VPN Director Bug?

[JohnD5000]

I recently upgraded from cable to fiber optic (Verizon Fios). I have a 500 DL / 500 UL plan. I was having a upload issue. I found it, it was QoS. Once I turned QoS off and removed the FlexQoS addin, the issue went away. However, when I was investigating for it, I might have found a VPN Director bug.
I am running a GT-AX6000 on merlin 3006.102.6.

The issue, when I use VPN Director, upload speed does not behave as expected. I have two rules, one for all devices, and one for my laptop (LG Gram). All testing is done through WIFI. The WGC5 rule is a Wireguard VPN

Here I have the two VPN Director rules turned off. A speedtest is done and I receive DL 510 and 574 UL speeds. These speeds are expected.

Here I have the two VPN Director rules set to WAN. A speedtest is done and I receive DL 515 and 571 UL speeds. These speeds are expected.

Here I have the VPN Director ALL rule set to WAN and Laptop rule set to VPN. A speedtest is done and I receive DL 500 and 503 UL speeds. I expect VPN to take a small hit. These speeds are expected.

Here I have the VPN Director ALL rule set to VPN and Laptop rule set off. A speedtest is done and I receive DL 486 and 391 UL speeds. The VPN should be engaged through the ALL rule. The DL speed seems reasonable, but I would expect the UL speed should be around 500, not 391

Here I have the VPN Director ALL rule set to VPN and Laptop rule set WAN. A speedtest is done and I receive DL 515 and 444 UL speeds. The VPN should NOT be engaged since the laptop rule should override the ALL rule. The DL speed seems reasonable, but I would expect the UL speed should be around 570, not 444

Here I have the VPN Director ALL rule set to VPN and Laptop rule set VPN. A speedtest is done and I receive DL 478 and 370 UL speeds. The VPN should be engaged since the laptop rule should override the ALL rule. The DL speed seems reasonable, but I would expect the UL speed should be around 500, not 370

End result, the VPN Director seems to work as expected for DL speeds, but whenever the VPN is set on the All rule, it slows down the UL speed significantly more than expected.

Use traceroute to evaluate routing. Speedtests are not a proper way to do so, as depending on your router model, some of that traffic might be forced to bypass HW acceleration.

Sorry, that is above me. I'm sure that I have something setup incorrectly. I'm not sure what I would be looking for. And I certainly, don't understand how a VPN Director rule would affect UL speeds.

BTW, I have a GT-AX6000 on merlin 3006.102.6. if it matters.

You have to accept the fact your AIO router can't consistently perform the way you want. It's a power efficiency optimized embedded device similar to RPi. You also have to re-evaluate your add-ons on this hardware platform and 3006 firmware. Running FlexQoS on it wasn't great idea for example.

But, what does your reply have to do with VPN Director? I showed that VPN Director behaves as expected when the VPN rule is just on the specific device. But the results are not as expected when the rule is on a larger group that includes that specific device, even if there is a specific rule that overrides that rule. I thought VPN Director just directs when and where a rule is used.

As explained by RMerlin above speed test is not a tool for routing evaluation. The fact VPN is involved already suggests performance impact. To what extent - it depends. Your FlexQoS for example had quite significant negative impact because on this platform since it requires Flow Cache disabled. What else is running on your router and in what configuration - unknown. Ignoring Speed Test - what else makes you think VPN Director in particular has a bug?
