        Diagnostics > Packet Capture:

        Interface: WAN

          @akuma1x said in opening ports on firewall:

          Alright, your NAT rules look correct, might want to make the protocol both TCP/UDP, and not just TCP.

          Your WAN rules are incorrect. Your FIRST set of 443 and 80 allow traffic to just your firewall, not another LAN machine. If you move these two new bottom rules to the very TOP of your firewall rule list, the traffic should move like you are expecting/hoping.

          Firewall rules are evaluated top down, first to match wins. That's why nothing is hitting 10.0.0.5, 80 and 443 are bouncing around inside the firewall itself, due to the first 2 top rules.

          Jeff

          Using the HA Proxy and not NAT the machine directly I don't think I need the firewall rule to the web server directly on the WAN. I have the NAT for port 80 and 443 disabled along with those firewall rules. I can put 2 new rules to wan to the webserver and see if that works.

            Using HAproxy is a completely different thing. In that case you would need rules passing traffic to the frontend(s).

                The first two WAN rules should probably be "WAN Address" instead of "This Firewall".

                Just a guess.

                    Just enough to show the traffic is hitting WAN.

                    If it is, then a pcap for the proper traffic on LAN.

                      Does this satisfy the wan is seeing port 80. My WAN IP is x.x.176.180

                        No. That's an outbound connection from your WAN address.

                          Its not that hard dude..

                          Can you see me .org

                          80towan.png

                          It shows closed because I don't have anything listening or forwarded.. But you can see the traffic gets there.

                            I am not seeing packets on port 80.

                            Looks like my isp is blocking or something else is blocking unless I am missing something else.

                            I have my cable modem plugged directly into my vmware server that is hosting the pfsense vm.

                              Just off the phone with suddenlink. Residential accounts are not able to open port 80. The same level of service for a business account for the same 1Gbps account is approximately 3x the cost. That is not reasonable.

                                What is the model of your cable modem? It is in bridge mode.. Correct?

                                  Quick google search says suddenlink pretty much sucks for this. Sorry.

                                  That's why we pcap. Nothing like making sure the traffic is actually on the wire before proceeding with additional troubleshooting.

                                      I didn't catch your post right before I asked. Can you use port 88 instead?

                                        I just need to figure out the SSL certs at this point with cloudflare service. I am not sure if I can use the acme service or not. I am hoping I can make it auto renew if needed. Does it make sense to use ssl offloading or just ssl on the front end?

                                        I am also looking at moving my open vpn to the HAProxy on 443.
