      I want to setup a firewall with a fixed IP on WAN as there is no DHCP on it. It is a 8 address subnet.
      I have 2 problems.
      If I test the firewall in a test environment  with WAN set to DHCP I can ping 8.8.8.8 but cannot access www.google.nl from a client. So DNS does not work. I have set the DNS servers in the system general setup page to 8.8.8.8 62.58.62.132 and 62.58.94.130.
      When I change WAN to fixed IP I get the message "no route to 8.8.8.8" . I have set the gateway on the WAN page to the gateway in the testnetwork.
      What else must I do to get things going?

      edit1: I found

      One possibility:
      If the router you're behind is indicating any kind of IPv6 capability pfSense will try to use it. It probably doesn't actually have that capability so you end up with nothing. Try this:
      https://doc.pfsense.org/index.php/Controlling_IPv6_or_IPv4_Preference

      Steve

      and that helped for the dns problem.

      edit2 for more info:
      When I set WAN to DHCP I get in the Status->Gateways 192.168.10.1 "On-line"
      When I set WAN to fixedIPv4 and I have put in the System->Gateways 192.168.10.1 at WAN I get in Status->Gateways 192.168.10.1 "Off-line".
      I did uncheck the box "Block private networks" in Interfaces->Wan.
      On a client I did route print and the output is the same for fixed and dhcp:

      C:\Documents and Settings\wk>route print

      Permanente routes:
        Geen

      But a tracert on the client stops in fixedIP after the firewall and continues in DHCP mode:

      C:\Documents and Settings\wk>tracert 8.8.8.8

      Bezig met het traceren van de route naar 8.8.8.8 via maximaal 30 hops

      De trace is voltooid.

      Why is there no route?
