      Today the connection speed to the server feel more faster (like normal speed)….but the performance when accessing to files on the server still not stable....I received this error few times when i open the excel file - "cannot be accessed. The file may be corrupted"  & The internet connection not stable, sometime microsoft outlook cannot send out the email, the mail pending in outbox. This few days, i will keep on monitor it.

      I'm using both type hostname & IP address.

      I'm not sure whether pfsense using routing or NAT...Please refer to below attached file for you to check.

        I'm not seeing any images, though if you don't know I'd guess NAT.

            Yes - and at the end of that link is an upload form, not an image.

              ok, nvm. Let me describe the settings.

              Firewall Advanced : Just follow by default setting..

              Network Address Translation : By default setting…Disable NAT reflection for port forward.

                It sounds like you're still NATing, which may be part of your problem. If you don't need it doing NAT try turning it off (though devices on 192.168.5.x will have to know how to route to 192.168.3.x).

                      To turn off NAT, just go to:

                      FIREWALL - NAT - OUTBOUND
                      There click "Manual outbound NAT", than click save. Then delete all existing rules in Outbound if there are any. Click save.
                      Thats it. NAT is turned off.

                      If you like to turn off NAt AND firewall, got to:
                      SYSTEM - ADVANCED - FIREWALL/NAT:
                      Disable Firewall.

                        After Turn Off the NAT, I'm still facing same problem… performance slow when accessing files on the File Server.

                        If i disable the firewall & Nat, i can't get the proxy report! Why? But for accessing file on the File Server will become more faster, like normal speed...!!

                        Can i just disable the NAT & Firewall, but i still can continue using squid to capture the traffic & proxy report ?

                          Did you try with bypassing squid for source/destination IP? Take a look if it will be faster then (even if NAT and firewall is enabled)

                              There isn't a possibility for bypassing the firewall for only some IPs as far as I know.

                                  It would help others if you could tell people how it was solved and what the problem was.
