Netgear UTM9S – ProSECURE Unified Threat Management (UTM) Appliance with DSL and Wireless modules Manual De Referência

Wrong network configuration

Verify that the Ethernet card driver software and TCP/IP software are both 

installed and configured on your PC or workstation.

Verify that the IP address for your UTM and your workstation are correct and that 

the addresses are on the same subnet.

Test the Path from Your PC to a Remote Device

After verifying that the LAN path works correctly, test the path from your PC to a remote 
device. From the Windows Run dialog box, type:

in which <IP address> is the IP address of a remote device such as your ISP’s DNS 
server.

If the path is functioning correctly, replies as in the previous section are displayed. If you do 
not receive replies:

Check that your PC has the IP address of your UTM listed as the default gateway. If the 

IP configuration of your PC is assigned by DHCP, this information is not visible in your 
PC’s Network Control Panel. 

Check to see that the network address of your PC (the portion of the IP address that is 

specified by the netmask) is different from the network address of the remote device.

Check that the modem or router is connected and functioning.

If your ISP assigned a host name, system name, or account name to your PC, enter that 

name in the Account Name field on the WAN ISP Settings screen of the single WAN port 
models or on one of the WAN ISP Settings screens of the multiple WAN port models. You 
might also have to enter the assigned domain name or workgroup name in the Domain 
Name field, and you might have to enter additional information. For more information, see 

Your ISP could be rejecting the Ethernet MAC addresses of all but one of your PCs. Many 

broadband ISPs restrict access by allowing traffic only from the MAC address of your 
broadband modem, but some ISPs additionally restrict access to the MAC address of a 
single PC connected to that modem. If this is the case, you need to configure your UTM 
to clone or spoof the MAC address from the authorized PC. You can do this in the 
Router’s MAC Address section on the WAN Advanced Options screen of the single WAN 
port models or on one of the WAN Advanced Options screens of the multiple WAN port 
models. For more information, see
