        Well if the netblocks are actually routed to you.. Then just create the routed netblocks and networks behind pfsense, and then all you have to do is all the traffic in the firewall

        So take one of those /29 or all 4 of them and put them on networks on the lan side of pfsense.

        So for example change pfsense lan interface to x.x.x.1/29 and then your clients on this network could be .2 - .6

        Or create a new optX network where this /29 will be connected behind pfsense.

              So what are you entering as the interface address and netmask?

              DO NOT set a source address/port in a port forward or firewall rule unless you KNOW you need it!

                public ip and the subnet mask 29 for example x.x.x.x/29

                  Ah. When you set that set IPv6 to none.

                  If you still get an error you are at least going to have to give us the last octet of the address there.

                    this error comes now

                    IPv4 address 167.114.2x.232/29 is being used by or overlaps with: WAN (167.114.21x.84/1)
                    This IPv4 address is the network address and cannot be used

                      So you have to find where that is configured.

                      Diagnostics > Routes might show you. That /1 netmask might appear as 128.0.0.0.

                        actually if i dnt use /1 netmask in wan side my wan ip does not response .. because my provider give me 255.255.255.255 mask and gateway is other subnet .

                          Not sure what to tell you there. That is unlike any ISP shenanigans I have seen before.

                          Maybe someone else knows.

                              @problemmaker What settings does your ISP propose? Ask them to come up with a decent solution (starting with your gateway).

                              Don't try to hack something together that might seem to work now. It will byte you in the long run.

                              BTW, you usually get a /32 mask with PPP links.
                              I have something like
                              111.2.3.4 /32 GW 111.9.8.7
                              on my WAN, and always had. Revert to that first and see why it doesn't work in your scenario. Once you figured that out the rest should be easy.

                                Forget it, Jake. It's OVH.
