      @23roadsdiverged the default rules are there, but your port forwards are a mess.. never going to work.

      What are your networks on your wan and lan.. What IP is trying to talk to what?

        I have cleared all but the default rules now. Will go check to see if printer works now...

        I was told by the Fire Panel company that the Fire Panel needs to be "whitewalled"... googling that term shows nothing. I believe they said it also needs to accept any incoming messages for it.

        WAN is one of the static IPs from Spectrum. 24.153.213.114 /29

        LAN is 10.0.0.1 /24

          @23roadsdiverged said in Confused about port forwarding:

          LAN is 10.0.0.1 /24

          Ok pfsense IP is 10.0.0.254? Why do you have a 10.0.0.251/32 IP setup on pfsense?

          What IP pfsense lan?

          What network are these fire panel or panels or fire panel servers sitting on? Do you need some IP on the public internet 1.2.3.4 or something that needs to talk to whatever the firepanel IP is that is on your 10.0.0 network behind pfsense?

            @johnpoz Fire Panel is both 10.0.0.251 and 10.0.0.254, from what I can tell. pfSense is 10.0.0.1.

            Multifunction printer is 10.0.0.201

            I was trying to get port forwarding to match what was on Netgear Genie.

            Netgear Genie Router Configuration (Port Forwarding and Triggering) 2023-05-31 120342.png

            Netgear Genie Router Configuration (Static Routes) 2023-05-31 120342.png

            Yes, but on the Netgear router I never needed to know/enter the public IPs that need to talk to the Fire Panel. From looking in Diagnostics -> States, it is attempting to communicate to two public IPs: 64.9.116.20 and 66.153.46.154 through port 5050. Doing a tracert, those lead to getting hung up on the following IP: 206-169-51-51.static.ctl.one [206.169.51.51]. The Fire Panel company did say that they had to turn off their receiving device due to it receiving thousands of messages that it cannot establish a full connection. And from what they have told me in the past, it needs to accept incoming connections on different ports than what it sends out on. I think.

                @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.

                bydefault.jpg

                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.

                            @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!

                              This packet capture is for when the printer is trying to send a scanned page out through the email.

                                Well clearly the printer is talking to the internet and dns there is it sending to and getting an answer.

                                Here is it talking to what is an email server because the port is 587.. 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.
