Rules invalid no interface *F0000B

CCR 6.36.3
We have something like that on OpenVPN Server
chain=input action=accept protocol=udp src-address=ip_ovpn_client dst-address=ip_ovpn_server in-interface=int_ovpn_client log=no log-prefix=“”
After rebooting a client we have
chain=input action=accept protocol=udp src-address=ip_ovpn_client dst-address=ip_ovpn_server in-interface=*F0000B log=no log-prefix=“”
But interface int_ovpn_client up after reboot.
How a fix this?

You need to go to PPP, plus button, then add an specific OVPN Server binding for that user, so that it creates a static interface for him/her regardless of OVPN connection being active or not; then you can later refer to such interface on any Firewall rules.

You’re absolutely right! )
Thank you! Thank you very much!
only CLI need interface ovpn-server add name=
