Document Name: Configuring Port Forwarding with the SonicWALL

This tech note provides information on how to configure your SonicWALL firewall for port forwarding of FTP, SMTP and DNS. Port forwarding is used when you have internal servers that need to be accessible by the public and you have limited public IP addresses. Therefore, a one-to-one NAT is not possible or not desired. In this scenario, only one public IP address is given and it is assigned to the SonicWALL WAN interface. However, we have three servers, one running FTP, one running SMTP and one running DNS that needs to be accessible by the public, as illustrated in the diagram below.
