        Firewall rules on LAN2 ?

        And show

        ipconfig /all
        

        on the PC connected on LAN2.

        @parneetbatra said in No Internet access to LAN2:

        LAN2: 192.168.100.1

        You've set more in then that ^^
        It's not just the IP. The 'mask' is set to /24, right ?
        DHCP LAN2 server ?

        No "help me" PM's please. Use the forum, the community will thank you.
        Edit : and where are the logs ??

            Here are the steps I followed:

            Interfaces -> Assignments -> Add a new LAN (example LAN2)
            Click on LAN2 ->
            - Enable: Enable interface
            - Description: LAN2
            - IPv4 Configuration Type: Static IPv4
            Static IPv4 Configuration
            - 192.168.100.1/25
            Save

            Services -> DHCP Server -> LAN2
            General DHCP Options
            - Enable: Enable the DHCP server on the LAN2 interface
            Primary Address Pool
            - Address Pool Range: 192.168.100.10 - 192.168.100.200

            Firewall -> Rules -> LAN2
            Copy LAN1 default rules IPv4* and IPv6* change source to LAN2, and click on Save.

              Let's start with :

              No Internet access to LAN2

              You've proven that wrong with :

              61f448c4-a65f-45b7-867e-8b5323aafead-image.png

              😊

              I saw :

              d626d93f-e02a-4997-a5b8-a68c88ba726b-image.png

              8a3fb559-d4ca-4b16-a8b2-b62d74198ef2-image.png

              When you did a :

              c91df92e-f25e-4ae8-8c13-cc7e773cf4db-image.png

              it showed that ICMP packets reach the LAN1, and the reply gets back. Good sign.
              Make it one step further : a ping from LAN2 to a device present on LAN1: the DNS pi-hole.
              I saw your PC was using this IP as a DNS.
              Another step : can your PC ping some other device on LAN1 ?

              Even more info : Goto Diagnostics > Packet Capture :

              Select for Capture Options your LAN2 interface :

              a6410135-0066-42ea-b37e-2de0a64d5dbb-image.png

              and hit the start button.
              Now, do a ping to google.com (this implies a initial host name lookup == DNS == 192.168.1.5 is/should (!) be used) or use the official Microsoft nslookup tool called nslookup ^^

              nslookup google.com
              

              What did that show ?

              and then look at the packet trace result.

              This might explain the issue : DNS packets coming from LAN2 do arrive at the LAN1 interface, but the pi-hole has a setting that allows it to answer only to requests coming from its own LAN == LAN1 == 192.168.1.0/24 - and it (pi-hole) refuses to answer to requests coming from elsewhere, notability 192.168.100.0/24 == LAN2.
              So pi-hole behaves like a black-hole ^^
              This pi-hole behavior is a security : it should only answer to request from the local "LAN" (LAN1) and from no one else. Up to you to add also "LAN2" (192.168.100.0/24) to the allowed network list.

              Btw : I never used or saw a pi-hole.

              No "help me" PM's please. Use the forum, the community will thank you.
              Edit : and where are the logs ??

                What do you get if you do an

                nslookup google.com
                

                ?

                I suspect, that your DNS is not responding due to missing ACL the LAN2.

                            Good news, if I change DNS to 8.8.8.8 in LAN2, I can ping to google.com
                            I can access the internet.

                            It's a Pi-hole issue. is there any idea for Pi-hole, why not let us connect to Google in LAN2?

                              You've identified your problem by drawing those two red rectangles around two Pi-hole log entries. Here is one of them:

                              ignoring query from non-local network 192.168.100.10
                              

                              As someone pointed out earlier in this thread, DNS servers such as unbound and Pi-hole have ACLs (access control lists) that limit what IP addresses can query for DNS names. By default those queries are limited to clients residing on the same local network (LAN) as the DNS server.

                              Scroll down this list of dnsmasque warnings in Pi-hole to find your specific error and its causes: https://docs.pi-hole.net/ftldns/dnsmasq_warn/.

                              The TLDR answer is you seem to have incorrect access permissions and thus DNS queries from your LAN2 are being ignored by Pi-hole.

                                  As said earlier,
                                  As said by @bmeeks
                                  As said by the guy who made the red box here :

                                  4155689b-487b-4282-bb84-a5141afac0db-image.png

                                  and as said by your pi-hole :

                                  "Ignoring query from non local network 192.168.100.1".

                                  The local network is 192.168.1.0/24 - your pfSense LAN network.
                                  So : request from 192.168.100.0/24 are ignored.
                                  So, set up pi-hole that it should consider both 192.168.1.0/24 and 192.168.100.0/24 as 'local'

                                  and from then on, DNS works on your LAN2 interface.
