Cellar Ports, Firewalls and Nat

Hi,

After installing karaf and installing cellar on a hosted VPS all works and the cluster commands are 
recognized. Also doing same on lan works.

Trying same on a remote system behind a firewall (local system modem) and forwarding port 5701 I can 
install and start cellar with SSH OK but the cluster command is not recognized.

Could this be related to port access or is something else suggested by the problem?

Also, is there available or contemplated a port forwarding feature for Karaf?

Hi,

By default, Cellar used multicast/unicast. In your case, to be able to
go through firewall, you have to enable tcp-ip in etc/hazelcast.xml.
