ICMP request not allowed

  • Hi,

    I was trying to access outbound PING but it was not allowed via PFSense. I already created a Firewall Rule but no to avail. Pls. see below the sample rule that i've created.

    Created a rule under WAN
    Protocol - ICMP
    Source - any
    Destination - WAN address

    I hope anybody can help me figure this out. Thanks

  • Can you post all your firewall rules?

  • OUTbound means to me that you are trying to ping from LAN to an IP somewhere on the internet, correct? Then you should have the allow rule on the LAN interface, never on the WAN.

  • Yeah - Basically you have allowed ICMP on the WAN which is often useful, but doesn't sound like this is what you want.

    The reason I want to see the rest of your LAN rules is because outgoing ICMP should work in a default setup unless you have made a rule that kills it.

  • Hi Guys,
    This is the only rules that i've got in my LAN…

    ID Proto Source Port Destination Port Gateway Queue Schedule Description

    * * * LAN Address 443
    80 * *  Anti-Lockout Rule

    IPv4 ICMP  LAN net  *  WAN address  *  *  none

    IPv4 TCP  ! AllowFBselected  *  BlockFBAlias  *  *  none    FB not allowed

    IPv4 TCP/UDP  LAN address  *  *  *  *  none    Allow LAN Outbound

    IPv4 *  LAN net  *  *  *  *  none    Default allow LAN to any rule

    IPv6 *  LAN net  *  *  *  *  none    Default allow LAN IPv6 to any rule

  • IPv4 ICMP  LAN net  *  WAN address  *  *  none

    You allow ICMP from LAN to the WAN address of your pfSense box, so the rest of the world is blocked…
