I have a need to monitor a lot of UPS units that are installed around the country at customer’s retail sites and I’m trying to figure out if NUT will do the job for me. The firewall I’m using won’t allow for a clean install of apcupsd (and I will admit I’d like some control over the systems, if possible). I’m trying to get NUT going but I am not sure if I am barking up the wrong tree. Ideally I’d have a ACL-protected port to call on the UPS remotely but some sites won’t allow for that so I’d need to have the ability to have it call my protected server as well. Any ideas? The firewall is pfsense (BSD, I know… but it’s serving us quite well right now at 30 locations) but the server can be anything I need it to be. Thanks! — Ryan
