Specify a range of client ports for communication.

Syntax

client_port=nnnnn[-mmmmm]

Protocols

• TCPIP, TLS, HTTP, HTTPS

Support notes

• Cannot be used in the ML directive of the Redirector.

Default

None

Remarks

Specify a low value and a high value to create a range of possible port numbers. To restrict the client to a specific port number, specify the same number for nnnnn and mmmmm. If you specify only one value, the end of the range is 100 greater than the initial value, for a total of 101 ports.

The option can be useful for clients inside a firewall communicating with a MobiLink server outside the firewall.

Example

The following example sets a 10000 port range of allowable client ports.

On a SQL Anywhere client, the implementation is:

dbmlsync -e "adr=client_port=10000-19999"

In an UltraLite application written in embedded SQL or C++, the implementation is:

synch_info.stream_parms = TEXT("client_port=10000-19999");
