  • 1.  Allow icmp packets in the filter

    Posted 10 days ago
    Hello,
     
    I wrote a filter for a constraint as follows
     
    set interfaces ae0 unit 0 family inet filter input closedaccess
    set firewall family inet filter closedaccess term access from source-address 192.168.1.2/32
    set firewall family inet filter closedaccess term access then accept
    set firewall family inet filter closedaccess term access_denied from destination-address 172.16.100.2/32
    set firewall family inet filter closedaccess term access_denied then reject
    set firewall family inet filter closedaccess term default-term then accept
    When I added the term for icmp accept, I couldn't get it to work, how do I accept all icmp requests from outside?

    Hi,

    Can you please share the filter configuration with the term to accept icmp? 

    Regards

    The filter above will deny all traffic to address 172.16.100.2/32.

    In filters once a match occurs all processing stops.

    So to allow icmp to 172.16.100.2/32 you would need an accept term just for icmp followed by the reject term above.
