      That is bizarre. I would expect there would also be 176.xx.xx.122 at the ISPs end, which you'd have to route to via that gateway. What kind of connection do you have?

      We have Radiolink connection, ISP installed a switch to our rack and told us to use port 1 or 2 to this connection. I've asked themto which technology I have to use for this connection but I can't get a proper reply.

        seems fairly common to me.
        10.59.126.136/30 is the transit network
        176.xx.xx.120/30 is your assigned subnet.

        you either use vip's & nat them; or you assign them to client devices on a seperate interface; or you can probably use the for a reverse proxy.

        or you don't use them at all

          It looks like he has 2 transit networks, one on 10. and one on 176..

          PfSense running on Qotom mini PC
          i5 CPU, 4 GB memory, 32 GB SSD & 4 Intel Gb Ethernet ports.
          UniFi AC-Lite access point

          I haven't lost my mind. It's around here...somewhere...

            I like to know is there is a configuration example for this type of connection. Does PfSense can handle this? I've checked the link, we're using opt1 interface for secondary ISP.

              The link provided has an example.
              Pfsense can handle this just fine.

              Perhaps you should explain what the problem is exactly. Also what do you want to do with your assigned public ipv4 subnet.

              Once that is clear, someone will probably ask for relevant screenshots of your current configuration.

                If the 176 subnet were, say, a /27 this would not seem unusual. The only odd thing here is that they appear to have given you a /30 routed subnet. Did you pay for some number of public IPs?

                You should still be able to connect from the transit subnet IP unless they are explicitly blocking that, which would be unusual.

                You should be able to connect from any IP in the 176/30 as a VIP on WAN.

                    I have one static IP. I've tried 176.xx.xx.121/30 as directly WAN interface IP but it doesn't ping the posible gateway(176.xx.xx.122). Also internet doesn't worked.

                      Yeah I've checked that example, thanks for the link. But It based on opt1 interface wasn't used scenario. In my setup unfortunately I'm using that interface for secondary WAN Link. I just want to connect Internet with new Radiolink ISP Setup.

                        The radiolink gateway shows as up I assume? (it responds to ping?)

                        When you ran that traceroute did you select 176.x.x.12x as the source?
                        If so it seems more like the provider has a routing issue.

                            Ok, well that looks good. What's not working then?

                            Seems like an issue with your outbound NAT config if other clients cannot ping 8.8.8.8. It must be NATing to the 176 IP.

                              I've couldn't detect what is not working, after upper comment the ISP installed additional router between pfsense and radiolink switch. Now we're using 176.xx IP for the WAN Interface. Thanks for all comments.
