Other than taking a screencap of my ruleset, and then retyping it all back in if I need to restore my system, does anyone know of a way to do this? Am I missing...

    Firewall Rules: Allowed IPs and Threat Prevention?

    Quick question, but probably one that betrays how little I actually understand Threat Prevention at the moment. If I create a firewall rule that allows traffic from a range of IPs, will threat prevention just ignore those? I use a particular remote desktop streaming service that's generating a...

    Excellent Series of Synology NAS Tutorials-Mydoodads

    I bought my NAS a year ago and realise that, amongst other aspects, permissions, Photo Station and Moments had created a year-long confusion; well permissions had, partly because I did not start with groups as I had only one or two users.
