      A friend of mine helped me set up PfSense (1.2.3) when I moved to a new apartment and everything worked fine except I can't open ports any more. At the moment I have everything set up like this:

      INTERNET
          |
      Switch(1) –-- IPTV
          |
      PfSense
          |
      Switch(2)
          |
      Computers

      I tried disconnecting the first switch(1) but it makes no difference, and from the little knowledge I have, a switch don't do anything with the traffic except passing it on. When I opened the ports the first time they showed up as "opened" in PFPortChecker (tool from portforward.com) but yesterday when I had some problems with Utorrent I decided to look up my ports. To my surprise all ports now return "Not Open" in PFPortChecker. I have no clue why they are now closed since I haven't changed any settings in PfSense.

      These are the settings:

      I can't see anything I have done wrong when comparing with this guide: http://doc.pfsense.org/index.php/How_can_I_forward_ports_with_pfSense%3F, and I don't know why they were open before and now closed?
      Does anyone have any idea what to do to make it work again?
      Thanks

      (Also, I don't know that much about this stuff so sorry if I don't understand your reply)

        The problem might be double NAT. If that is the case, it might be open on the pfSense FW, but is not being forwarded by the internet router. There is not enough information on your setup to really know.

          I use PfSense as the router and modem if thats what you mean? I am not using the one you get from your ISP. Everything I have is in the set up in post one, I have no other router or firewall in-between except the switches as shown in the setup.
          "INTERNET" is the fibre optics from my ISP (Not sure what you actually call it)
