Network problems

This section contains tips on ways you can troubleshoot a
networking problem.
Problems communicating with remote IP hosts
Verify the accuracy of the default gateway's IP address (entered
in the IP Setup or Easy Setup screen).
Use the Netopia Router's ping utility, in the Statistics, Tests,
Utilities screen, and try to ping local and remote hosts. See
"Ping" on page 10-3
utility. If you can successfully ping hosts using their IP
addresses but not their domain names (198.34.7.1 but not
garcia.farallon.com, for example), verify that the DNS server's
IP address is correct and that it is reachable from the Netopia
Router (use ping).
If you are using filters, check that your filter sets are not
blocking the type of connections you are trying to make.
Local routing problems
Observe the Ethernet LEDs to see if data traffic flow appears to
be normal.
Check the WAN Statistics and LAN Statistics screens to see
more specific information on data traffic flow and address
serving.
If you are using MacIP subnetting, make sure Transmit RIP is
On (see the IP Options screen).
