This option is provided for connections across firewalls, as firewall software filters according to TCP/UDP port. It is recommended
that you do not use this protocol option unless you need to for firewall reasons.
The ClientPort option designates the port number on which the client application communicates using TCP/IP. You can specify
a single port number, or a combination of individual port numbers and ranges of port numbers. For example:
It is best to specify a list or a range of port numbers to make multiple connections using a given Data Source or a given
connection string. If you specify a single port number, then your application will be able to maintain only one connection
at a time. In fact, even after closing the one connection, there is a several minute timeout period during which no new connection
can be made using the specified port. When you specify a list and/or range of port numbers, the application keeps trying port
numbers until it finds one to which it can successfully bind.
