      It worked !

      Thanks one more time, you advice was insanely helpful. Made it work, and though I was about to give up I slept it up and once refreshed it sort of everything clicked it became so easy and logical, it's just all the looping around server to server that makes it seem more complicated than it is, huh?! 🤓

      I also went a little further set it up to proxy internally as well to simplify web addresses. And the best yet is that I finally came up with a solution to both use the naked domain for Active Directory and to host a website in it without hosting it on the DCs.

      I'm leaving some screenshots, hopefully I can help somebody else too. :)

      Missing something? Word endings, maybe? I included a free puzzle in this msg if you solv--okay, I'm lying. It's dyslexia, makes me do that, sorry! Just finish the word; they're rarely misspelled, just incomplete. Yeah-yeah-I know. Same thing.

        I have not updated my haproxy config in quite sometime and i used your @PiBa template for offloading and endpoint termination http config that's online in the wiki. is this still up to date or is could this be done differently now?

          There are always options to do the same things differently. But there should not be a 'need' to do so unless you like that way better. Its not like the package changed significantly.

            i'd really would love to see an updated tutorial from you, since you are by far the most advanced user of the package :D

              What would you like to see updated? Is there something specifically that is missing that should be explained to basic users to get started?. If some pages are 'outdated' i can give it a go at creating a few new screenshots.. but really almost nothing has changed with regard to the basic frontend+acl&action>backend configuration stuff.. from whats already explained on my wiki pages..

                @Piba, well i am not sure, tbh as i am not to experienced with haproxy it self. I played around with map files, on a standalone system that seemed to work alright too. Not sure if that has an advantage in regards to sni vs offload.

                I used haproxy mainly to serve a couple of webpages with subdomains, and i created a virtualip for haproxy 2.1.1.2, maybe you can check if i didnt build in some obvious mistakes or forgot to tick somethings on.

                  @Piba,

                  I have a specific question regarding the HAProxy setup, In your wiki https://github.com/PiBa-NL/pfsense-haproxy-package-doc/wiki/pfsense_2_3_haproxy_sni_plus_offloading_backends you forward your request that arrive on wan side on port 80 and 443 to the address 192.168.0.133, my question here is, what is this ip, is it an ipalias in your network outside of the dhcp range that haproxy is listening on, or a virtual ip on the lan interface that haproxy is listening on. Would you mind guiding me.

                    In my case 192.168.0.133 a virtual-ip of type alias on the pfSense WAN interface, of a test VM that runs with its wan on a private network segment.. Usually you would use the wan-ip of pfSense for that listening. Or wherever you want that haproxy frontend to listen.. Some websites i run with haproxy listening on the lan-ip, as they only need to be accessible when connected to the company network.. So its really up to you, where are your clients going to connect to, and do you want haproxy to directly handle that traffic, or are your going to create a portforward (though imho thats kinda ugly.., but then again, ive heard of haproxy failing to listen directly on a pppoe interface iirc..).

                      @piba I would like to do it the pretty way, right now i create a virtual ip (ip alias) on the wan interface that is an ip that is outside of my network (lan 192.168.0.0/24) my ip alias is 2.1.1.2/32 then i have a nat portforward from wanadress to 2.1.1.2 of port 80 and 443 and have haproxy listen on that. I guess thats the ugly part :D

                        Yup sounds 'ugly' 😉
                        But well, shouldn't be to difficult to change that and make the frontend listen on the wan-ip right.? add a firewall rule to allow the traffic, and remove the portforward.

                          @PiBa Thanks for your time and help ! And for the nat rule you just say allow 80/443 to any (e.g. *** http *** and *** https ***)

                            So the firewall-rule it would look like:

                            interface: WAN
                            protocol: TCP
                            source-address: any
                            source-port: any
                            destination-address: wan-ip
                            destination-port: 80 (or 443.. or what you want to allow traffic to.)
