      Yup, and that shouldn't be an issue.

      I assume you are able to ping other addresses?

          @okjello Is the IP address you're trying to ping the specific monitoring IP address for the Bypass Gateway?

            Mmm, it responds to ping fine for me and @johnpoz so not something pfSense specific.

            Can we see your firewall rules? Do you have anything specific for that IP?

              I did try to setup allow rules for this ip as i connect to this server on port 16567. I couldn't connect with or with out rules I made. I can connect to other game servers. it soo strange. I might just try reload pfsense as i have nothing really configured on it.

                138.197.130.124

                So I just reloaded pfsense, I installed 2.6.0-RELEASE on a toshiba laptop with i5 cpu and a usb nic.

                Every webpage and thing I ping works except 138.197.130.124.

                Normally I would think my public ip is being blocked etc but i can unplug the uplink from cable modem to pfsense and plug my computer directly into cable modem and i can ping that ip all day long.

                only thing i configured is the wan and lan with loccal ip 10.1.0.1/23 everyting else except password in out of box config....

                  @okjello sniff on wan while your sniffing - do you see the ping go out? If so then its not pfsense..

                        @okjello sniff on your WAN!!

                        Do you see the echo request go out? Its that simple - yes or no? You said you can ping google, so why would you would think showing us that?

                            WAN icmp 64.66.xxx.xx:44889 (10.1.0.45:1) -> 138.197.130.124:44889 0:0 8 / 0 480 B / 0 B

                            If your showing state then that means it went outbound - if it went outbound and you don't get a response that has ZERO to do with pfsense.

                            You plugging a different device into a cable modem gets you a different IP.. Because your mac changes.

                            I want you to sniff on pfsense wan so you see the traffic go out for yourself.. This isn't a pfsense issue.. This is upstream.

                            Just think for 2 seconds.. What thing could be wrong on a clean install to some IP, but every other IP works..

                              Are you sure the public IP is the same in both situations?

                                Tell you right now they are not.. Why would a dhcp server give a different mac the same IP?

                                He shows pfsense having a public IP in his wan state.. In what scenario would different macs from a dhcp server get the same IP?

                                What makes more sense - IP X blocked by this server, or pfsense just deciding to not work on some random IP, but creates the outbound traffic, as you can see via the state..

                                  Yup that seems most likely. Though you would think the laptop running pfSense would also get a different IP and be able to connect. Just unlucky maybe....

                                    @stephenw10 where did he say he used a different laptop then previous? He just telling you what he is running pfsense on, and that he reinstalled it.

                                    He didn't say he changed the nic being plugged into the cable modem..

                                        @stephenw10 If I was handicapping this - just a blocked IP would be the super-duper AAA 5 Star lock of the decade.. While odds of it being pfsense would be the long shot of the century.. Like betting your Shetland pony is going to win the Kentucky derby ;) Make that not just the derby but the whole triple crown ;)

                                          I agree the whole thing is strange, I see the ping go I do not see reply, but would pfsense not have to pass the reply back? You can ping that ip on pfsense right? If i put my cisco rv042 back in place i can ping and get replies when i put pfsense in i can't. That is what i find strange.

                                            Do you see the same public IP in use when using the Cisco though?
