As soon as I saw that white thingy with two antennas I was like "hold on a second!". How is the speed for you? I set it up as a repeater with single-hop VPN and just ran cloudflare's speedtest (I'm connecting from a hotel's wifi). I got:
41.6 dl 44.8 up 14.0 latency 4.84 jitter
At first I setup openvpn and it was like 3mbps laggy very laggy. But wireguard for some reason makes it fly.
Are you using gl.inets own configuration program or openwrt's luci?
are you looking for ngrok.io by any chance? when was the last time you saw your ngrok.io and will it bite me if i approach it too fast?
