I like my Asus router RT-ac59u, because of the openVPN feature. To be more specific, I use the VPN as client. not Server.
But I have a tp-link that deals better with quotas.
In Asus you can limit quota per device (bandwidth - not auto) fig 1; or use auto. quota (QoS), but it is not per device, it its per usage type (download etc. [in some routers this has two branches traditional or Adaptive QoS ]). So it simply does not work well for several devices (fig 2). (those two modes [Bandwidth vs QoS] do not work at the same time) asus emulator, QoS
So, the Asus has quotas per device (Bandwidth), but they do not adapt to the current situation (number of active devices, etc) (fig 1), or, the automatic system (QoS) that does not work well (one device can get most of the bandwidth in practice) (fig 2).
In tp-link, by contrast, you set a min. and max. for any or all devices (IPs), and it guarantees you an uniform distribution of your bandwidth. But I have not OpenVpn in that router. (fig 3) tp-link emulator
Anyone knows a model with both characteristics (tp-link quota and openvpn as client)? The tp-link Archer AX1500 won't work. Does not have VPN (Openvpn) as Client, only server.
