I currently use the Slate and Brume and also ordered the Flint. One feature which i would love to have is multiple wireguard VPN instances running at the same time. This is a very helpful feature to have and only a very few routers support this feature.
OpenWRT can do this, but I do not think the glinet webgui can do this.
It also requires some work to setup policy based routing using OpenWRT’s MWAN3 package to configure the required routing for multiple gateways to function.
Running different vpn profiles are easy.
But routing is the problem.
This is where it could be handy with network segmentations/VLANs.
