On OpenWrt 18.06-SNAPSHOT r6996-b295e3a, I've installed wireguard. After configuration and reboot, I receive the following on the command prompt:
root@OpenWrt:~# wg
interface: test_wg
on LuCI:
Interface test_wg
Configuration Interface does not have a public key!
Config:
config interface 'test_wg'
option proto 'wireguard'
option private_key 'xxxxxxxxxxx='
list addresses '192.xxx.xxx.xxx/32'
config wireguard_test_wg
option public_key 'xxxxxxxxxxx='
list allowed_ips '0.0.0.0/0'
option endpoint_host 'xxxxx.xxxxx.xxx'
option endpoint_port '22222'
option preshared_key 'xxxxxxxxxxx='
