PFSync Interface
pfsyncinterface
Synchronize Enabled
pfsyncenabled
PFSync transfers state insertion, update, and deletion messages between firewalls. Each firewall sends these messages out via multicast on a specified interface, using the PFSYNC protocol (IP Protocol 240). It also listens on that interface for similar messages from other firewalls, and imports them into the local state table.

NOTE: Clicking save will force a configuration sync!
checkbox
Synchronize Interface
pfsyncinterface
interfaces_selection
If Synchronize State is enabled, it will utilize this interface for communication.
<br><b>NOTE:</b> We recommend setting this to a interface other than LAN! A dedicated interface works the best.
<br><b>NOTE:</b> You must define a IP on each machine participating in this failover group.
<br><b>NOTE:</b> You must have an IP assigned to the interface on any participating sync nodes.
pfSync sync peer IP
pfsyncpeerip
input
Setting this option will force pfSync to synchronize its stable tables to this IP address. The default is directed multicast.

checkbox
Synchronize to IP
synchronizetoip

input
Note: CARP sync is currently only supported over connections using the same protocol and port as this system - make sure the remote system's port and protocol are set accordingly! Also note that you will not use the Synchronize to IP and password option on backup cluster members!
Remote System Password
password
Enter the webGUI password of the system that you are synchronizing with.
