      Hi dear pfSense powausers,

      this is my first post on this forum. Please apologize me if I don't respect somehow rules established here… I will try to be as understandable as possible.

      I'm trying to figure out how to create a simple firewall ruleset that would allow me from the SSH console of my brand new pfSense box to ping webserver on the Internet.

      First, here's my setup :
      INTERNET Provider 1 ----- Cisco Router |
                                                                    | ---- pfSense Router ---- LAN
      INTERNET Provider 2 ----- Zyxel Router |

      Cisco Router is actually not up since Internet Provider 1 is still testing optical fiber

      Zyxel WAN IP : 192.168.100.2
      Zyxel LAN IP  : 192.168.0.1

      pfSense WAN IP : Statically configured, but actually down (no carrier)
      pfSense OPT1 IP : 192.168.0.10 (dynamically attributed by Zyxel DHCP Server)
      pfSense LAN IP : 192.168.1.1

      WAN+OPT1 is configured as a gateway group with following priority :

      WAN : tier1
      OPT1 : tier2

      I've got a computer on LAN that can access web, mail, ping, DNS Query, i.e everything from LAN to (WAN-OPT1) : everything works as expected.

      My pb is the following (note, I'm connected on my pfSense box through SSH)

      ping www.google.fr
      PING www.google.fr (74.125.230.248): 56 data bytes
      ping: sendto: No buffer space available
      ping: sendto: No buffer space available
      and so on....
      

      I can execute DNS query from this pfSense box :

      host example.com
      example.com has address 192.0.43.10
      example.com has address 2001:500:88:200::10
      

      But ping, traceroute (ICMP in general) seems to be denied.

      Moreover, I wanted to see which packages are available, but the web GUI (/pkg_mgr.php) tells me :

      Unable to communicate with www.pfsense.com. Please verify DNS and interface configuration, and that pfSense has functionnal Internet connectivity.

      My question is : what firewall rule has to be created to allow traffic (any kind of traffic) directly issue by this router to access the whole Net ?

      Thanks for reading.

      Regards.

        Seems to be solved…

        I changed OPT1 to default gateway under System -> Gateways -> Edit Gateway.

        At the moment I can do all kind of traffic from SSH access without restriction.

        Regards.
