      Dear,

      I have setup pfsense firewall and i have connected wan interface from my modem and lan interface from my internal IPs. On internal Lan interface i have assigned static ip. Before setting up pfsense i was able to access public ip from my internal lan but now after setting up PFSENSE i am not able to ping my public ip from my internal lan.
      even internet and all things are working properly at my internal lan, i am able to open google etc.

      1- public ip natted in modem
      2- i have public ip (WAN interface) DHCP enabled
      3- i have internal IP (LAN interface static ip)
      4- Dhcp enabled on internal lan ( for internal systems)
      5- Not able to ping public ip from my internal lan

      So please give me solution to ping public from my internal lan.

      Thanks
      Hitesh …

        what does that have to do with dhcp or dns?

        Are you saying your external IP fqdn is not resolving?

        1- public ip natted in modem
        2- i have public ip (WAN interface) DHCP enabled

        Confused so your double natting, or pfsense has a public IP as well?

        Have you modified your lan rules?  Out of the box pfsense will not answer ping to its wan IP.. You would have to create a rule on its wan to allow icmp to its wan address.  Do you have block rfc1918 enabled on wan?

          Dear

          Thanks for reply…

          I found 5 questions from your site -

          1- may be it doesn't related to dhcp and dns ? but i have written this post in DNS and DHCP because i have no idea of this issue.

          2- yess fqdn with (public ip ) is not resolving and pinging from internal lan .

          3- double natting is not there, we natted only on modem and pfsense has no public ip it is directly connected with modem with DHCP option and modem have public ip and its natted there.

          4- We have not modified LAN rules.

          5-  we have not block rfc1918 enabled on wan.

          Kindly help me out of this ...

          Thanks ..

          Hitesh

            @hitesh:

            even internet and all things are working properly at my internal lan, i am able to open google etc.

            If everything is working properly why do you need to be able to ping your public IP from inside your network?

              "3- double natting is not there, we natted only on modem and pfsense has no public ip it is directly"

              Huh??  That is a DOUBLE nat..

              You may get better help in your native lang area…

              "2- yess fqdn with (public ip ) is not resolving and pinging from internal lan"

              How wold it PING if can not resolve??  I suggest you move to your native language area..
