Example – HTTP and HTTPS Traffic to the Internet

To allow HTTP and HTTPS connections from the local 192.168.200.0/24 network to the Internet, the Barracuda Firewall must perform

source-based NAT. Instead of using the source IP address from the client residing in the LAN, the connection is established between the WAN IP

address of the Barracuda Firewall and the destination IP address. Reply packets belonging to this session are replaced with the client's IP

address within the LAN.

For this example, use the predefined connection object. It automatically uses the WAN IP address of the ISP uplink with the Default (SNAT)

lowest metric according to the Barracuda Firewall's routing table.

Service Objects

A service object contains a list of TCP/UDP ports for a service. To reference network services when you create firewall rules, you can use the

predefined service objects. If you want to reference custom services that are not in the default list or services on a non-standard port, you can

create custom service objects.
