Confused about port forwarding

@23roadsdiverged you don't need to know the public IPs that want to talk to some internal IP, unless you want to lock it down.. But there is nothing in your rules that would stop 10.0.0.x from talking to some public IP.. But if you need the public internet to be able to talk to 10.0.0.254 that is behind pfsense.
Then that would a port forward on your wan (wan address), that forwards the port to that IP..
example.
by default pfsense would create the wan firewall rule to allow the port forward
There is no reason you would need a "route" to get to 10.0.0.251, because pfsense knows how to get to anything on your 10.0.0.0/24 network because it is attached to it.

@johnpoz Ok, I have cleared out all misconfigured NAT rules and now have only the block Bogon and RFC 1918 ones showing. I then added the rule you described. Here's another thing I don't understand... in the Netgear, this 10.0.0.254 address was not listed in the IPv4 leases... but the 10.0.0.251 was. But the fire panel worked just fine. The 10.0.0.9 IP address listed in the port forwarding also was listed in the IPv4 leases, so I am not sure what that was for (it is also outside of the DHCP range).
-
@23roadsdiverged, if the device is setup up as static IP on the device, then no it wouldn't be listed in some dhcp servers lease table.
-
Sorry, what I meant was in the Netgear it was listed under "Connected Devices" with the static IP, along with all other connected devices, whether static or dynamic IP.
In Netgate/pfSense, the only similar screen I have found is the DHCP leases, I don't see where to access a similar "Connected Devices" page like what the Netgear had. But yeah, pfSense only lists static IPs on that list if I manually configure a device that initially shows up as a dynamically assigned IP.

@23roadsdiverged Check the ARP Table.

@rcoleman-netgate Ok, so when I looked, sure enough the 10.0.0.251 was not showing up in the ARP table. Feel dumb that I didn't realize the "Connected Devices" on the Netgear is the ARP table... I then reassigned the MAC address to 10.0.0.254, and it shows active and now shows up in the ARP table.... I will see if that, combined with the proper port forwarding from @johnpoz allows communication. Ty both!

So whatever your problem isn't a firewall issue.

@johnpoz OK, ty, yes. It turned out to be a password issue. Thank you for your help. Now I just need to figure out the fire panel.
