A snapshot is an image of the complete system at the time of creation that tracks changes and can be restored if needed.

No problem.
Be sure to set a cron job for updating the DNS Blocklists, running zcrubs, smart tests, and trim if you are using a ssd.
I am working on a way to do snapshots for the system as well for super simple restores that are automatically created. Before an update you WILL want to have a snapshot available. Once snapshots are automated I will probably start doing automatic updates. It basically creates a system similar to how an immutable OS works, if something goofs you can simply roll back to a previous working state and pause updates. I previously had a script I setup via a cron job but the system removed the job during an update.

Try setting a tunable of:
net.link.ether.inet.max_age = 540
By default FreeBSD sets a 20 minute ARP maximum age while many ONT’s set a 9 minute maximum age. This will show up as performance issues initially then cause other issues.
Also Realtek NIC’s are notorious for issues with FreeBSD, so if you are using one replacing it with an Intel one is highly recommended.

Absolutely. Remember to enable a cron job in the OpnSense - System > Settings > cron to update the Blocklists. Otherwise you are likely out of date.
