Configuring the Junos OS to Extend the Default Port Address Range
By default, the upper range of a port address is 5000. You can increase the range from which the port number can be selected to decrease the probability that someone can determine your port number.
- To configure the Junos OS to extend the default port address
range, include the source-port statement at the [edit system internet-options] hierarchy level:[edit system internet-options]source-port upper-limit upper-limit;
upper-limit upper-limit is the upper limit of a source port address and can be a value from 5000 through 65,355.
