      skipper,

      I think that load balancing by definition has to use NAT, so creating a NAT rule manually would conflict with the automatically created settings used by load balancing.

        @skipper:

        if i remove that how will it work?

        The virtual server will listen on wan interface ip.

        If you create a nat, the you will have two services "listening" on the same port/ip

        Create the virtual server and then create a wan rule to allow traffic to it with no nat.

          i disabled the NAT rule and created 2 rules on the wan interface, first one destination wan address and the second one destination virtual server so i have not blocked package on the FW but still it doesn't work.
          from my vpn connection i can access the virtual server but not from internet so i am a bit confused :S
          do i need to setup something more?

            Did you changed pfsense gui port and disabled WebGUI redirect to avoid conflict with your http redirect?

            Is 192.168.100.100 your wan address?

              In your network, is the site-to-site a VPN or a point to point connection? They seem to be in different networks, so you are going to have to make sure that your routing and NAT reflect this.

                i am accessing pfsense via http and the virtual server is listening to https so i think no conflict there (System: Advanced: Admin Access, protocol http).
                how do i disable WebGUI redirection?
                192.168.100.100 this is virtual's server ip, my wan address has an internet ip.

                  it's a vpn site-to-site. there is routing between the 2 networks so the web and web-slave can see each other. do i need an additional routing rule?

                    Create another virtual server with wan ip and it will work.

                      hey marcelloc thnx a lot, it's working!!
                      i cannot access the web-slave from internet but i can access it from web's network.
                      do i have to create some nat or routing about that?

                        What status you have on loadbalance for the web-slave?

                        status -> loadbalancer

                          the status is enable and accessible (green 100%) that's why i don't understand.

                            i found out that when an https request is going to web-slave through the vpn, then the web-slave is trying to send the package through the wan interface and not back to vpn. can i somehow force this traffic to pass through the vpn connection?

                              You will need an outbound nat to "masquerade" client internet ip. This way the server can return the package through vpn instead of forwarding it to it's wan

                                how must the outbound nat look?
                                these are the vpn IPs
                                pfsense1 ip : 10.4.0.1
                                pfsense2 ip : 10.4.0.2

                                  It's on firewall -> nat -> outbound

                                      change source to any.
                                      does webslavelan is the outgoing interface to reach 10.4.0.0/30?

                                        thnx for your help man!
                                        this is my network a bit more detailed,
                                        i have tried to put different interfaces and IPs on the outbound configuration but the traffic goes still to my wan :/
                                        now i put vpnsitetosite as interface and source any but it doesn't work.
                                        what should the destination be? is there something else that i need to define? create a new gateway or something like that?

                                          Try to go to console and do some package capture to find what interface pfsense is using to send traffic to remote host.
