since a few days we have communication problems between an application and centera. Both tcp/udp port 3218 are open, telnet works, the PEA file works between centera node and replication node. but when I try jcenteraverify on the application host with the pea file I got this error. error within the application: "EMC CENTERA NOT FOUND AT POOL ADDRESS" or "error on network socket hostname/nn/POOLINFO". can this be firewall related, maybe some changes ?
