Barracuda Link Balancer

When are inbound rules automatically created for NAT rules on the Barracuda Link Balancer?

All Barracuda Link Balancer models, firmware version 1.2 and above

When you add a 1:1 NAT rule on the Services > NAT page, an Inbound Firewall rule is created automatically to accept traffic for the private IP address of the server. Without this rule, all connections that are initiated from outside are denied. You can view and change this rule ? it has a similar Rule Name ? using the Firewall > Inbound page. You may want to modify that rule to limit access to only those ports or applications that you want to be publicly accessible.

Additional Notes:
1:1 NAT rules are not executed if the Barracuda Link Balancer firewall is disabled.
