Problem Troubleshooting Suggestion
Internet Access
PC cannot access Internet Use the ping utility, discussed in the following section, to
check whether your PC can communicate with the Internet
Security Router’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 the Quick Start Guide chapter,
Part 2 for instructions on viewing the IP information.) If it is
not, correct the address or congure the PC to receive IP
information automatically.
• Verify with your ISP that the DNS server specied 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 Internet Security Router to translate the
private address to your public IP address. The assigned
IP address must be within the range specied in the NAT
rules. Or, congure the PC to accept an address assigned
by another device (see section 3.2 “Part 2 — Conguring
Your Computers”). The default configuration includes a
NAT rule for all dynamically assigned addresses within a
predened pool.
PCs cannot display web
pages on the Internet.
Verify that the DNS server specied 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 ISP’s DNS server.
