KNXD avec une passerelle N148/22

[tru]

KNXD_OPTS=" -D -T -S -b ipt:<ip_de_n148>"

Take the newest v0.12 (stable branch) which is 0.12.14 at the moment.
For your IP interface you need ipt: (tunnel unicast). ip: is for multicast.
You also need -e and -E. If you have systemd it will take care of unix socket and inet socket, otherwise you would need -i or -u. Look at the readme on https://github.com/knxd/knxd/tree/stable.
