Settings to make InfluxDB accessible from WAN

I have InfluxDB 2.3 running fine on a PC. I created a Grafana Cloud instance with the hopes of viewing the data. To do this, I need to make my InfluxDB accessible via WAN, so I created a port forwarding rule in my router and all seems to be correct. However, Grafana Cloud still cannot see it.

Do I need to do something with the config file (maybe this?) in InfluxDB to allow connections from outside the LAN? FWIW, here are my settings:

File in /etc/influxdb/config.toml

bolt-path = "/var/lib/influxdb/influxd.bolt"
engine-path = "/var/lib/influxdb/engine"

hey Grant

I would feel very leery/uncomfortable about such a setup from a security pov with a simple forwarding config on your router.

imho I would say this is more networking issue than influx or grafana
