I can be much more specific if needed but has anyone had a problem with a firewall sitting between a RAC cluster and your workstation causing host name to change? Let be clarify that. My TNSNames file has both nodes addresses in it. I connect via SQL*Plus to the name associated to this entry. A listener trace on my system show it being sent. A trace on both nodes shows it being received. The trace from, lets say node 1, show the connect command being received. It then does a redirect via server side load balancing and sends the connection info back to me indicating that I will be connected to node 2 and port 1234. When this packet gets back to my system the trace shows that the packet just sent indicates I should connect to node 1, not node 2 that was just sent, and that it should be on the port that was just sent(it comes across without being changed). Odd, it seems like the packet is being changed in transit.
