No nat (NOT) > Enabling this option will disable natting for the item and stop processing outgoing nat rules.
Hint: in most cases, you'll not use this option unless you know what you're doing.
Interface
Choose which interface this rule applies to.
Hint: in most cases, you'll want to use WAN here.
Source
Type:  
Address:   /
  Enter the source network for the outbound NAT mapping.
Source port:   (leave blank for any)
Destination > not
Use this option to invert the sense of the match.

Type:  
Address:   /
  Enter the destination network for the outbound NAT mapping.
Destination port:   (leave blank for any)
Translation
Address:  
  Packets matching this rule will be mapped to the IP address given here.
If you want this rule to apply to another IP address than the IP address of the interface chosen above, select it here (you need to define Virtual IP addresses on the first). Also note that if you are trying to redirect connections on the LAN select the "any" option.
Port:  
Static-port:   >
  Enter the source port for the outbound NAT mapping.
No XMLRPC Sync >
HINT: This prevents the rule from automatically syncing to other carp members.
