At this moment secure communication is only possible via Multicast. Secure Tunnelling is not supported yet so for ETS programming you will have to temporary disable the "Enable only secure communication" option.
On central LM you can enable any of the IP > Local filters in "Accept" mode and leave the filter table blank. This will block all incoming IP telegrams. On other LMs allow 1.1.1 and 1.1.2 in IP > Local, block any outgoing telegrams to minimize the traffic and enable "Filter local update telegrams".
Make sure that all LMs have NTP enabled and working correctly. This is needed for the encryption to work.
For improved network security you can look into VLANs.
