Reviving an old thread, since I am faced with a similar issue and am having trouble getting my head wrapped around it..
We recently started experimenting with Ignite and have a 2 server cluster setup on AWS with s3 based discovery, config for one of those servers looks like below: (The addressResolver has the server's own private and public address-55.55.555.1) <property name="discoverySpi"> <bean class="org.apache.ignite.spi.discovery.tcp.TcpDiscoverySpi"> <property name="ipFinder"> <bean class="org.apache.ignite.spi.discovery.tcp.ipfinder.s3.TcpDiscoveryS3IpFinder"> <property name="awsCredentials" ref="aws.creds"/> <property name="bucketName" value="ignite"/> </bean> </property> <property name="addressResolver"> <bean class="org.apache.ignite.configuration.BasicAddressResolver"> <constructor-arg> <map> <entry key="10.0.0.12" value="55.55.555.1"/> </map> </constructor-arg> </bean> </property> </bean> </property> Config on the other server looks very similar, except for that servers own private and public ip's-55.55.555.2 Both can talk to each other and the cluster comes up just fine, able to Visor to connect to the cluster etc Now to the problem, I am trying to connect a client from my local to the cluster using Visor, this is the config on the local: <property name="ipFinder"> <bean class="org.apache.ignite.spi.discovery.tcp.ipfinder.s3.TcpDiscoveryS3IpFinder"> <property name="awsCredentials" ref="aws.creds"/> <property name="bucketName" value="ignite"/> </bean> </property> <property name="addressResolver"> <bean class="org.apache.ignite.configuration.BasicAddressResolver"> <constructor-arg> <map> <entry key="10.0.0.11" value="55.55.555.1"/> <entry key="10.0.0.12" value="55.55.555.2"/> <entry key="10.10.10.120" value="24.55.55.160"/> (local client's private and public IP) </map> </constructor-arg> </bean> </property> Port forwarding is also established on the client side, and telnet to server ip's and ignite port, telnet to client's public ip and ignite port works fine. Visor comes up and connects to the cluster fine, but when trying to do Top, this is the error I am faced with: class org.apache.ignite.IgniteCheckedException: Failed to send message (node may have left the grid or TCP connection cannot be established due to firewall issues) [node=TcpDiscoveryNode [id=bcb110e3-55ff-4a5b-8d1b-d180485e1373, addrs=[0:0:0:0:0:0:0:1%lo, 10.0.0.11, 127.0.0.1], sockAddrs=[/0:0:0:0:0:0:0:1%lo:47500, /127.0.0.1:47500, /10.0.0.11:47500], discPort=47500, order=1, Which tells me that it is trying to talk to the Servers on their private IP's and not their public IP's, which should have been resolved by AddressResolver, what am I missing here? -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/
