Beryl AX how to install luci-app-strongswan-swanctl for IPSec VPN

i want to install luci-app-strongswan-swanctl on my Beryl so i can get a IPSec VPN connection on it configured via the GUI. any idea how to install it ? i tried adding the openwrt repo but it didnt work.

I’me trying to do that, from a vanilla OpenWRT (not Gl.Inet fork),
But it’s not (yet) working
See my post

by the way, my test of luci-app-strongswan-swanctl
is very negative.
It’s very early GUI, based on the UCI interface to /etc/config/ipsec

the problem is that this UCI interface does nor support much, not EAP as I need.
Moreover it seems using the old strongswan/ipsec configuration format…

I’m battling with the more recent configuration format in
/etc/swantcl/conf.d
