I’ve managed to set up a baikal server to sync my calendars and tasks instead of using a free cloud service provided by nextcloud. I’m able to reach it from beyond my local network, but this is all very new to me and I’m a little worried about what permanently leaving a port open for this.

I’m hoping to find some resources for securing this, before leaving it up all the time. I suppose as an alternative I can always only run it at home and only sync when I’m home but this seems less ideal.

Thanks a bunch for the help in advance. I really appreciate it.
