  • Last updated on

Use Barracuda Firewall Admin to configure your unit. Do not configure your system with the acpfctrl utility unless you are advised to do so by Barracuda Networks Technical Support.

To view information and settings for the firewall module (acpf), use the acpfctrl utility.

Options

start

Starts the acpf module and imports the Forwarding Firewall rules and access cache.

stop

Stops the acpf module. The firewall is stopped. Rules and the access cache are saved.

The acpf can only be stopped if its dependent services are also stopped. Before using the acpfctrl stop command, block the firewall services on the server and on the system by using the phionctrl module block firewall and phionctrl box block boxfw commands. For more information, see phionctrl.

parp show

Displays all proxy ARP entries for the firewall.

[root@ash:/var/phion/logs]# acpfctrl parp show
           noext 10.0.10.208/4 MVPN
noping show

Displays all IP addresses that are set to noping.

bacl show

Displays all box access control list entries.

lproto show

Displays the locally handled IP protocols.

realm show

Displays the device realm assignment. The following realms are available:

  • 0unknown
  • 1intern
  • 2dmz
  • 3extern
  • 4persvpn
  • 5fwvpn
  • 6iptun
  • 7usr
device

Displays information about all devices for debugging.

plugdebug

Dumps debug messages of a specified plugin to the appliance firewall log.

  • acpfctrl plugdebug <plugin name> 1 – Enables the dumping of debug messages.
  • acpfctrl plugdebug <plugin name> 0 – Disables the dumping of debug messages.

The output for the plugdebug parameter is used by Barracuda Networks Technical Support.

param

Displays the parameter settings for the appliance.

version

Displays the acpf version.

[root@chefix:~]# acpfctrl version
PhionVersionString R-3.2_V-3.2.0.1 Nov  8 2005 18:53:18
tune kernel

Checks the Use Kernel Ruleset parameter in the operational settings of the general firewall configuration and displays the status.

  • acpfctrl tune kernel on – Temporarily enables the Use Kernel Ruleset function until reboot.
  • acpfctrl tune kernel off – Temporary disables the Use Kernel Ruleset function until reboot.
tune vpnbypass

To properly use tcpdump to troubleshoot or monitor VPN traffic, all VPN traffic must be handled by one CPU. Only use this option temporarily because disabling vpnbypass considerably reduces the performance of the VPN service.

  • acpfctrl tune vpnbypass on – VPN traffic is handled by multiple CPUs.(default)
  • acpfctrl tune vpnbypass off – VPN traffic is handled by a single CPU, allowing tcpdump to show all VPN traffic.
vrf

The partial command vrf provides a subset of more vrf-related commands:

The following commands are to be exclusively used by authorized Barracuda Networks Support experts only!

Do not use the following commands unless you are authorized by Barracuda Networks Support experts!

acpfctrl vrf create   [vrfname] [vrfid] – Creates a VR instance with the given name and ID.

acpfctrl vrf delete   [vrfname] – Deletes a VR instance with the given name.

acpfctrl vrf exec     [vrfname] [cmd] (restricted to acpfctrl commands) – Executes a shell command in the context of the named VR instance.

acpfctrl vrf identify [pid] – Shows the VR instance a user is connected to via the CLI.

acpfctrl vrf event – In case there are events available for the VR instance, this will produce a list.

acpfctrl vrf show – Lists all VR instances configured on the box.
