      well if your setting static on a lan pc, you need to give it a gateway (normally this would be pfsense IP on that network segment - ie lan)

      yeah without that your not going anywhere other than other ips on that segment.

      This normally handled via dhcp, but if doing static

      Lets say your pfsense lan IP is 192.168.1.1/24

      So your pc you might make 192.168.1.19/24
      gateway 192.168.1.1
      dns 192.168.1.1

      And you should be good to go.

          if you don't have a gateway set on the pc then its NOT Possible for them to get to the internet, unless they are using a proxy that is on their local lan and that is what is giving them internet.  For example if you point to pfsense as proxy and your running proxy on pfsense then you could get internet that way.

            Thanks
            yes i'm using proxy squid and that computers are joined to windows domain who automatic generate script for that computers with gpo with proxy adress in browser .
            so if I disable the proxy adress from the browser and don't put the gateway with statut ip all will be ok ?

              if no proxy and no gateway then there is no way for them to get off their segment, so no internet.

                couldn't the internet be blocked though the firewall for that IP 192.168.1.19/24?

                  not if using a proxy no..  Proxy is the one going to the internet not 192.168.1.19

                  Normally if you have a proxy you control internet access as the proxy with user auth, etc.  Not by removing the gateway.  And your firewall rules would only allow the proxy to go out anyway, etc.

                        so you denied them access at the proxy, and then rules at the firewall to block any non proxy traffic that might go out.

                        Normally in work place all direct traffic would be blocked from all clients, and only exceptions would be made for non proxy away applications or things that don't work with the proxy.  Proxy is where you content filtering would be done, if you allow clients to not use the proxy and direct go out the internet then very simple for them to bypass your content filtering and surf p0rn for example.

                          I don't get what's this "schedule" good for. Just set up a permanent block rule for those. Why are you scheduling something for 24/7?
