      Hi.
      I have installed the latest version of pfSense on VMware workstation pro, together with several other VMs. I am using the pfSense for firewall_router for my GNS3 lab topology, together with the other VMs as hosts in the GNS3 lab topology. The problem is when the pfSense VM is on, the Intenet access on the host machine stops - can not access Internet pages. I am using an usb wireless adapter for connecting to the router, becouse there are no cables to the router in the room, where the host machine is located. I am using the pfSense from 2 years on other host machines again with several VMs working together with the pfSense and this has never happened. Where can be the problem?

        If you simply shutdown the pfSense VM the host can access again?

        IP conflict? Multiple DHCP servers?

          Yes. When i stop the pfSense, i can access the Internet on the host machine. When the pfSense is on, the network icon of the Windows is showing that the host machine has access to the Internet, but when i try to open an Internet pages, it can not be open.
          No there are no IP conflict, because the WAN port of the pfSense and the host machine get different IP addresses.
          There is only one DHCP server that gives different addresses to both of them.

            Some ARP conflict then maybe?

            The host have an interface in the pfSense LAN? Maybe that is set as the default route?

              Both are in the same LAN, but both have different MAC addresses - the WAN port of the pfSense and the adaptor of the host machine.

                And no other adapters the host sees dircetly?

                About the only thing I could imagine is that the host has a NIC connected to the pfSense V< such that when it's powered up it sees that as linked and tries to use it by default.

                  The strange thing is that i used this kind of configuration on an other host PC, with fewer VMs and this problem did not occur. Then the version of the pfSense was older.
