3. Click Update. Once the SonicWALL has been updated, a message confirming the update is
displayed at the bottom of the browser window.
If you receive an error when you click Update, confirm that the HomePort Address Range does not
include the SonicWALL WAN IP Address, the WAN Gateway (Router) Address, or any IP addresses
assigned on the One-to-One NAT or Intranet windows.
Tip The SonicWALL supports up to 64 HomePort address ranges.
Configure the computers on the HomePort with the IP addresses provided by your ISP. Remember
to enter HomePort IP address as the default gateway IP address.
HomePort in NAT Mode
The SonicWALL HomePort now has the ability to use private internal IP addresses rather than public
IP addresses on the network. Since NAT hides the true IP addresses in use on the network, NAT on
the HomePort is an additional security feature for the SonicWALL. The outside world only sees the
outside public IP address of the DMZ and not the internal private addresses.
To configure the HomePort in NAT Mode, use the following instructions:
1. In the HomePort Private Address field, enter the private internal IP address assigned to the DMZ
interface. The default address of 172.0.16.1 is appropriate for most networks.
2. Assign a subnet mask in the HomePort Subnet Mask field. The WorkPort and the HomePort can
have the same subnet mask, but the subnets (private IP addresses) must be different. For
instance, the WorkPort subnet can be 192.168.0.1 with a subnet mask of 255.255.255.0, and
the HomePort subnet can be 172.16.18.1 with a subnet mask of 255.255.255.0.
3. If you choose to use HomePort NAT Many to One Public Address (Optional), enter the HomePort
public IP address which is on the same subnet as the WAN for access to devices on the
HomePort interface. HomePort NAT Many to One Public Address is only available if your
SonicWALL is configured in NAT Enabled networking mode on the WorkPort.
Configure your computers connected to the HomePort to reside on the same subnet, i.e. have an IP
address from the HomePort IP address range, and enter the HomePort IP address as the default
gateway IP address.
Delete a HomePort Address Range
To delete an address or range, select it in the Address Range list and click Delete. Once the
SonicWALL has been updated, a message confirming the update is displayed at the bottom of the
browser window.
