It is not possible to open one port multiple times.
You can bind multiple ip addresses to your host and bind all programs to one specific ip address.

Another option can be to add another program which bind to your port 3601 and open the three programs at different ports. This additional program can receive incoming data and forward it three times, one to each of your instances.
