NAT for LAN Servers
Network Address Translation (NAT) for LAN Servers allows you to automatically NAT all servers on the LAN with a single setting. This option enables all traffic originating from LAN to go out on the WAN, automatically NATted with the WAN interface IP address or with the first available Service IP address.
You are not required to configure SNAT and ACL rule for the LAN servers, as the Barracuda Web Application Firewall automatically NATs and allows the LAN traffic to go out on the WAN. For example, consider the LAN servers with the IP addresses 10.10.10. 24, 192.168.32.10, and 192.168.30.15. To go out on WAN through the Barracuda Web Application Firewall, the traffic from the LAN servers is automatically NATted with the WAN interface IP address (220.127.116.11) or with the first available Service IP address 18.104.22.168.
NAT for LAN Servers can be enabled in the NETWORKS > Network Configuration page, Network Configuration section.
