If you are NATing the firewall rules are applied before the nat, so it could see the connection as between an internal and another internal address, and deny it. I seem to recall that we needed to have ICMP enabled and several other things for the upfront handshaking to work.

Hope that helps.

any protocol rather than sqlnet or 1521 it work good only sqlnet is not working, i a can ping or telnet the server but i cant make a sqlnet connection
