The question is, how does one use this service? Web app or phone app only?

No.

Lucid Chart

HA cloud. Apple iCloud storage.

IMO, no. I don’t use pfsense on a daily basis (MikroTik FTW), but netgate will use CE as a testing ground. They’ll keep putting out updates; but advanced functionality will be paywalled.

‘Sense’ uses interface to base their rules around. You could use the vlan interface or the wan interface for this.

Running suricata and HAProxy will be the cause of your slowness / wierdness.

Unlikely.

And?

Vaultwarden. Been using it self hosted for 3 years.

Ilulz. Automated scans cost nothing in resources. That would not find a host IP, it’d find the public Ip and open port.

Nothing will stop a general scan from happening. Especially if it’s a slow scan.

Scans won’t trigger dos/ddos alerts.

The only thing a CF tunnel does is protect your home IP. Doesn’t protect the app or server you’re exposing.

Not so much will someone be assed about it, it’s whether a script will pick you up your server. There’s a ton of aggregation search engines that scan most IPv4 addresses and list them on what ports are open etc. such as Shodan.io

Like I said, safeish.

Meh. Safeish. Until one of your servers has a zero day.
