Troubleshooting TZ 180 Configuration and Settings Issues
15 SonicWALL TZ 180 Recommends Guide
In NAT mode, use an address from the private ranges (10.0.0.0/8, 172.16.0.0/16, 192.168.0.0/24) and
assign the OPT interface a private address from this range. This is the address you’ll use as the gateway for
devices attached to the OPT interface. By default, the firewall allows LAN resources to access the OPT
resources, but not the other way around. If the appliances on the OPT interface need to access LAN
appliances, a firewall policy to allow it must be created. Likewise, if resources on the OPT interface need to
be accessed from the WAN, a firewall rule will have to be created. It is recommended that you use the Public
Server Wizard to do this, because it creates the necessary rules for NAT, firewall, and loopback (the special
rule that allows internal resources to contact the server on the OPT interface using its WAN IP address).
Verify that the OPT Interface Is Connected
Navigate to the Network > Settings page and verify that the Status displays as connected . For example,
Figure 7 provides a view the OPT interface as no link , indicating a connectivity problem. Check the cabling
and any other network equipment that joins the two together.
Figure 7 OPT Interface Is Down
Symptom: I Have One Public WAN IP Address, the TZ 180 Is Already Using the HTTP
and HTTPS Ports for Management, and the Ports Are Needed for an Internal Server
Navigate to the System > Administration page and set the HTTP and HTTPS Web management ports to
something non -standard, for example, 8080 and 40443. When accessing the appliance using the
management interface, append these ports onto the end of the management interface address.
