Connecting the SMA on an Existing
DMZ
The following procedures explain how to configure your gateway on an existing DMZ:
• Connecting the SMA to the Gateway
• Allowing WAN to DMZ Connection
• Allowing DMZ to LAN Connection
Connecting the SMA to the Gateway
To connect the SMA using Scenario B:
1 Connect one end of an Ethernet cable to your DMZ, either directly to the corresponding port on your
existing SonicWall gateway appliance, to a hub, or to a switch on your DMZ.
2 Connect the other end of the Ethernet cable to the X0 port on your SonicWall SMA 210/410. The X0 Port
LED lights up indicating an active connection.
3 Configure the SMA X0 with an IP address in the DMZ subnet. Refer to Configuring the X0 IP Address for
more information.
Allowing WAN to DMZ Connection
If you are already forwarding HTTP or HTTPS to an internal server and you only have a single public IP address,
you will need to select different (unique) ports of operation for either the existing servers or for the SMA
appliance, because both cannot concurrently use the same IP address and port combinations.
To allow a WAN to DMZ connection:
1 Log into your gateway appliance as an administrator and click the Wizards icon at the top right of the
interface.
2 On the Welcome page, select the Public Server Guide, and then click Next.
3 On the Public Server Guide page of the Wizard, select:
The Add Service Group dialog box is displayed.
