Troubleshooting Suggestion
• Verify with your ISP that the DNS server specified
for the PC is valid. Correct the address or
configure the PC to receive this information
automatically.
• Verify that a Network Address Translation rule
has been defined on the RX3042H to translate
the private address to your public IP address.
The assigned IP address must be within the
range specified in the NAT rules. Or, configure
the PC to accept an address assigned by another
device (see section 3.2 "Part 2 — Configuring
Your Computers"). The default configuration
includes a NAT rule for all dynamically assigned
addresses within a predefined pool
Verify that the DNS server specified on the PCs is
correct for your ISP, as discussed in the item above.
You can use the ping utility, discussed in the following
section, to test connectivity with your ISPʼs DNS server.
If you have not changed the password from the
default, try using "admin" as the user ID and "admin"
for the password. Otherwise, you can reset the
device to the default configuration by following the
instructions provided in section 10.6.1 "Restore System
Configuration". WARNING: Resetting the device
removes any custom settings and returns all settings to
their default values.
Use the ping utility, discussed in the following section,
to check whether your PC can communicate with the
RX3042Hʼs LAN IP address (by default 192.168.1.1). If
it cannot, check the Ethernet cabling.
Verify that you are using Internet Explorer 6.0 or newer.
Support for Javascript® must be enabled in your
browser. Support for Java® may also be required.
Verify that the PCʼs IP address is defined as being on
the same subnet as the IP address assigned to the
LAN port on the RX3042H.
Be sure to click on "Apply" button to save any
changes.
