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 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 Internet Security Router 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.

PCs cannot display web

pages on the Internet.

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 ISP’s DNS server.
