INFO: Viewing firewall filtering options - Internal

  • Description
    When networking problems occur, one may want to review the firewall filters integrated into the Finjan appliances.

  • Symptoms
    Network problems occur such as no response to/from a finjan appliance or while the device is working and communicating with other network resources.

  • Cause
    Finjan appliances are equipped with an integrated fully-capable firewalling mechanism which may be blocking connections due to a malfunction (not so probable as firewall rules seldom change) or due to a manual override.

  • Solution
    To view the firewall filters on a Finjan appliance type:

    iptables -L -nvx

    NOTE: 
    1. The iptables command is also used to change the firewalling rules, DO NOT use the iptables command to perform any other operation other than the one stated above unless approved by PM or R&D.
    2. iptables rules are defined via the GUI->Devices->IP->Acces list tab and limited shell  command access_list
