Full satisfaction after 15 days of advanced use
The performance is there for a mixed personal and telecommuting use for 2 people: direct internet access, VPNs, simultaneous video meetings,
The flexibility of use and configuration is also there, thanks to OpenWRT which is easily installed. I tested DD-WRT which is not functional on this router.
Under OpenWRT, the security is there with the basic functionalities (in 1 click) of firewall and DMZ, but also advanced functionalities of network-wifi guest, segmentation of the tele-working networks (mixed wired-WiFi) between them and vis-a-vis the personal network, ipV6...
In short, at my level (I am not a test lab), total satisfaction and good value for money.
