's LAN IP address (by default [192.168.1.1]). If it
cannot, check the Ethernet cabling.
If you statically assigned a private IP address to the computer,
(not a registered public address), verify the following:
- Check that the gateway IP address on the computer
is your public IP address (see Quick Start, Configuring
Your Computers on page 15 for instructions on viewing
the IP information.) If it is not, correct the address or
configure the PC to receive IP information automatically.
- 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 ADSL Barricade 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 Quick Start, Configuring Your Computers on
page 15).
The default configuration includes a NAT rule for
all
dynamically assigned addresses within a predefined
pool (see the instructions to view the address pool).
