Our security guys mandate that only the needed ports is opened on each servers local firewall.

It would be nice if we could configure port ranges for inter cluster communication so that we can comply with the firewall policies.

Currently there is no support for that but doable. At least we can
force hazelcast to pick an outbound port in a way that it is not a
potential inbound port.
You may want to create an issue for this.

The same requirement from security dept. here! Unfortunately, this is K.O. criteria, so we need to solve it somehow.

When can you implement this feature?

Thank you, so far very satisfied with Hazelcast.
