Scope:
All Barracuda Web Application Firewalls running firmware 7.7 version

Answer:
When a customer configures source NAT on WAF backend servers will be allowed access to the internet via WAF. If you want to block your server from accessing certain IP's then we have to configure Network ACL's as mentioned below.


1. Navigate to "Advanced -> Advanced Networking" page.

2. Select "System" from 'Network Group' under 'Network Configuration'.

3. Now click on 'Add ACL' under 'ACLs for Forwarded Traffic'. Here you can specify the source and destination IP addresses and destination port numbers that has to be Blocked/Allowed.
