    Just noticed this when I tried to add another port to my open TCP ports list – saving the list fails with the error message Character not allowed in tcp port definition. Allowed characters are numbers, ":" and "," if the list would become longer than 255 characters (ISPConfig 3.1.15p2 on Ubuntu 16.04 LTS).
