convert MDT KNX IP Interface to multicast IP interface with KNXD

[fluppie]

Can I use knxd to "convert" my current MDT IP Interface to a multicast IP Interface. I have a Raspberry Pi 3B available for this task. So the RPI3 would make a connection to the MDT IP Interface and then broadcast all bus/group messages over Multicast IP.
Or is this not the right software to do this?

From reading some doc, I made this, but it doesn't work:
KNXD_OPTS="-e 15.15.50 -E 15.15.51:18 -u /tmp/eib -b ipt:192.168.1.5 -S"

KNX IP-Interface
Status Programming Mode: Off
Change Programming Mode:

Individual Address 15.15.255
Tunneling Addresses
15.15.241
15.15.242
15.15.243
15.15.244

Looks like

KNXD_OPTS="-D -T -R -S -e 15.15.200 -E 15.15.201:10 -b ipt:192.168.1.5 -S"

Is working for me. Is this the right way? Or was I lucky ?

Yes that looks OK besides the redundant -S at the end.

Actually, you should put the whole -DTRS at the end. Individual drivers and their flags should be used after global flags like -e/-E.

Ok. Thanks, I updated to:

KNXD_OPTS="-e 15.15.200 -E 15.15.201:10 -b ipt:192.168.1.5 -DTRS"
