SQLNet Protocol

SQL*Net Protocol

The SQL*Net protocol is used by Oracle clients and servers to query SQL databases. This advanced protocol mainly uses a single port for communication and should therefore not be an issue for the ASA engine. However, that port can be redirected to a different port or a different server during the connection lifetime. To allow traffic to pass securely, the fixup protocol sqlnet command is used to help monitor SQL*Net protocol connections. The following is the syntax for this command:

 pixfirewall(config)# [no] fixup protocol sqlnet <port-[port]> 

The following example enables SQL*Net inspection of port 1521:

 pixfirewall(config)# fixup protocol sqlnet 1521
