        am i right that the problem resides, when upper picture config is in use? if so, then add that dns service, like ericab mentioned
        if the other picture rules is in use and is creating problems, then try to ping from firewall itself to 8.8.8.8 and www.google.com

            well i have fully working settings, and even i'm not capable of pinging www.manager.co.th, so that address don't allow icmp echo.
            did you tried ping also from client?

                well ping can't work only tcp connections.. it's done by icmp and udp53 works faster than tcp53

                what you have selected to in those rules, to capture a log?

                  Thank you. But it same can't to access internet.

                  you need to switch the protocol to UDP.

                  do your clients obtain their IP through DHCP, or are they setup up independently ?

                  if you were to ssh into pfSense, can you ping anything ?

                    "- pfsense 2.0 Release(1wan,1lan) + Squid proxy + Firewall Rule."

                    if you wanting your clients to use squid proxy, they would not be directly accessing anything on the internet anyway.  Why would they not be using your pfsense box for dns?  And or the proxy should be doing the dns lookups anyway.

                    If you wanting for clients to access the net while using a outside dns server, you rules need to allow for tcp http (80), and tcp/udp 53 (dns) to whatever dns server you wanting them to use say 8.8.8.8

                    But not understanding the point of the proxy if that is what you want to do?

                      By default the firewall rule blocks. So if you disable the default allow rule, then it stops working. If all you want to allow is surfing, then LAN NET:any any:80|443|53 though with port 53 you need UDP and TCP. If you want to test ping, you must have an allow rule for ICMP.

                        Thank you, All Comments.

                        Now, The pfsense 2.0 Release + Squid proxy + Firewall Rule can access to internet.
                        I disabled "Default allow LAN to any rule" and allow TCP port 80,53,UDP port 53,ICMP.

                            "Squid proxy"

                            Still not understanding if you using a proxy why your directly letting machines out?  Who are you having use the proxy?
