Ip Router Communication Problem

[savaskorkmaz]

Hi,
We have one Logic Machine try to communicate with 3 different KNX IP Router via IP routing mode. All IP routers are in route mode. Logic machine and IP Router are using IP Blocks. But network switches are allowed to communicate for different IP Blocks. We can send ping from Logic Machine to IP Routers. But we cannot get KNX communication from IP routers.

What should we do ?
How we can communicate from different IP Blocks with Logic Machine for KNX IP routing ?

Routing is using multicast with default TTL (Time To Live) set to 1. You can change this value in KNX connection settings (System Config). Routers and some switches decrement TTL values for each packet. When TTL reaches 0 the packet is discarded. Different IP sub-networks do not matter for multicast communication.
