Change the network interface that PaperCut NG/MF listens on
PaperCut NG/MF listens on all available network interfaces by default. If your server has multiple IP addresses (i.e. is multi-homed), PaperCut NG/MF accepts connections to all these addresses. Alternatively, you can configure it to listen on a single, defined interface. To configure PaperCut NG/MF to listen on a single network interface:
