      Hello everyone,
      I just wanna start by saying I'm a network super noob. This is the setup I have at the moment. I have an isp router/modem out of that router I have a poweredge server plugged in via a lan connection. On this server I am running hyper-v core. I have several VM's PFsense included. Now My isp leases IP in the 10.0.0.* range the gateway is 10.0.0.1 I have a virtual lan and virtual wan. I kept getting an overlap error message so I set the lan to 10.1.1.1 now theres no overlap the wan is set with dhcp 10.0.0.128. Now with those IP's I can reach the internet from VM's I can ping my local computer which is 10.0.0.182 but when trying to ping from my local computer to the PFsense box It doesn't work. I thought maybe it was a firewall rule but I deleted all rules blocking connections from a private network. Still will not talk to the PFsense VM. I am pretty sure its an ip conflict or something. Does anyone have any ideas on how I could get this rolling?
      Thanks in advance

        @jimbo-1 You would need to show us your firewall rules.

        pfSense+ 23.09 Lenovo Thinkcentre M93P SFF Quadcore i7 dual Raid-ZFS 128GB-SSD 32GB-RAM PCI-Intel i350-t4 NIC, -Intel QAT 8950.
        pfSense+ 23.09 VM-Proxmox, Dell Precision Xeon-W2155 Nvme 500GB-ZFS 128GB-RAM PCIe-Intel i350-t4, Intel QAT-8950, P-cloud.

          So your local computer is connected to the WAN subnet of pfSense. By default pfSense doesn't allow any access from private networks on WAN.
          This is set in the WAN interface settings by "Block private networks". You have to remove this check.

          Also there is no rule on the WAN allowing anything by default. To enable access you have to add a proper pass rule to the WAN interface.

          Further consider that accessing the virtual network behind pfSense from your computer requires that you add a static route on the PC for the LAN network pointing to the pfSense WAN IP.

            @viragomann Just take a screen shot of your firewall rules ... a picture is worth a thousand words.

              Alright so since you asked me to take screen shots I noticed at the bottom it says all incoming connects will be blocked until a pass rule. I have no Idea what that means. I guess it did have to do with the rules.

                @jimbo-1 Please look at this to restore your default firewall:
                https://docs.netgate.com/pfsense/en/latest/config/factory-defaults.html

                Then read these:
                https://docs.netgate.com/pfsense/en/latest/firewall/best-practices.html
                https://docs.netgate.com/pfsense/en/latest/recipes/example-basic-configuration.html

                You need to be able to talk to LAN net.
