📋 Additional Information (optional)

Peers did not have internet connection (handshake was ok) in alpine-wireguard LXC when installed with verbose OFF. silent function probbably was not working with this line.

"$STD echo "net.ipv4.ip_forward=1" >>/etc/sysctl.conf"

So the config was mising in LXC. I removed it to test and now it works.

  • I also moved related code to wg install, since you need this also if you dont install wgdash.
  • I also added rc-update add sysctl for reboot persistance. recommended here

Bug only happened on running the script with NO verbose.
