I am using an Arcus-EDS KNX-GW-IP-2TE now, and the module written by Donald.Peter works fine with this gateway.
This module doesn't need ETS5 for configuration, it has a handy web interface.
Thank you Donald.Peter, you saved me weeks of coding.
is knx multicast address (188.8.131.52) supported in your module?

OK, now I tested the brandnew Serial and IP Gateways from the german AMX distributer. Here is the link:
the serial gateway can handle up to 1000 KNX addresses and the IP version can handle 3000 addresses. In my actual project I control 1950 addresses and everything works fine and stable.
There are some more intersting features:
