Narrowing the ZeroMQ port range
Striim uses ZeroMQ for communication among servers and Forwarding Agents.
By default, ZeroMQ uses the port range 49152-65535. To narrow that range, on each server in the cluster, edit striim/conf/startUp.properties, find the line # ZMQ_PORT_RANGE=49152-65535, remove the #, and set the ports as desired. Do not set the low value below 49152 or the high value above 65535.
Firewall settings:
Striim servers must allow inbound access for this range
systems on which Forwarding Agents are running must allow outbound access for this range
Then restart the server, as described in Starting and stopping Striim Platform.
