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: - 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.
- iptables rules are defined via the GUI->Devices->IP->Acces list tab and limited shell command access_list
