Hi, You can configure TcpCommunicationSpi:
TcpCommunicationSpi communicationSpi = new TcpCommunicationSpi(); communicationSpi.setLocalAddress(localAddress); communicationSpi.setLocalPort(cc.getCommunicationLocalPort()); communicationSpi.setLocalPortRange(cc.getPortRange()); Please take a look at documentation: https://ignite.apache.org/releases/latest/javadoc/org/apache/ignite/spi/communication/tcp/TcpCommunicationSpi.html#setLocalPort-int- Best Regards, Andrei -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/
