@whoami-idk Hello! It looks like you are trying to get the connecting VPN client's username for IPsec/L2TP mode. ipsec trafficstatus will not show this information, because user authentication is done by xl2tpd/ppp, not IPsec (Libreswan). This feature is outside the scope of this project and not supported. For more information, refer to this issue.

If you want to disable IPsec/L2TP mode, refer to Select VPN modes.
