If you are running a DPPT server, you need to allow incoming connections to ports:
4561/TCP on the local machine hosting the DPPT server.
5001/TCP on the local machine hosting the DPPT server.
NB. Note that port 5001/TCP can be changed in the config.bat file with the 'set port' command.
If you are running a DPPT master or DPPT client, you will need to connect to ports:
4561/TCP on the DPPT server.
5001/TCP on the DPPT server.
NB. Note that port 5001/TCP can be changed in the config.bat file with the 'set port' command.
