Slow VPN on RT-BE92U

[PuraVida]

The setup is, in addition to the RT-BE92U is gigabit fiber coming from a Huawei OptiXstar EG8041X6-10 ONT. There are no Entware or AMTM add ons. The router see in the mid 900s and minus VPN that's essentially what a client gets. But connect with VPN and speeds to clients drop into the mid 100s. I have two VPN providers, Surfshark and Nord. I have tried OVPN UDP and Wireguard from both providers. Speeds vary as you'd expect but no drastic improvement. I've disabled the router firewall with no joy there either. I'm on the latest Merlin firmware, 3006.102.6. While the ONT has wireless capabilities the ONT is running in bridge mode. The ISP by default uses non routable addresses for client but public IPs are available for a small fee which I have added. What I have no way of knowing is how, even in bridge mode, routing is done. When the ISP put the ONT in bridge mode it did not disable DHCP or wireless. This is my first experience with Huawei ONTs and know little about them. As an FYI, I'm in Costa Rica.

I would appreciate any ideas or thoughts

The joy may come shortly.

Can we assume , the router firewall is back on as it must be ?

Yes. Since the tech at the ISP weren't very convincing that they knew exactly what bridge mode is and does I verified the firewall on the ONT is disabled.

The ONT state is unrelated to your VPN speed issue. Bridge or Gateway - doesn't matter for your VPN Client. Enable the firewall on your ASUS. VPN speed is not guaranteed. There are external limiting factors unrelated to your hardware capabilities. Test with x86 hardware (VPN Client application on a PC) to the same servers and see if the speed goes any higher. If it doesn't - the servers you connect to limit the bandwidth.

The reason I mentioned bridge mode is because having only user permissions I can't disable the firewall and I don't have access to the admin level GUI to put the ONT in bridge mode. I also haven't been able to get an answer from them if they treat VPN traffic differently. I'm going to reset the router and see what I end up with. Because even when I go out on a network not on VPN speeds still drop. By comparison I also have a cable modem with 300Mb download and I tupically got between 325 and 350. Connecting to VPN with the same router and same config speeds only dropped to 300 sometimes a little more. I expect a speed hit going through VPN just not 800 Mb. Fiber down here costs double what I can get cable for. So, if I can't solve this it makes no sense to stay on fiber when I get more usable bandwidth from cable.

Why do people ask questions BEFORE they have tried simple things?

Reset is unlikely to solve the issue, but I would like to come down to Costa Rica and assist with the procedure. Two weeks should be enough time. And I already have experience with the fire ants...
