Verify the accuracy of the default gateway’s IP address (entered in the IP Setup or Easy Setup screen).

Use the Netopia R5000 Series Router’s Ping utility, in the Utilities & Diagnostics screen, and tr y to Ping
local and remote hosts. See

“Ping” on page 14-2

for instructions on how to use the Ping utility. If you can

successfully ping hosts using their IP addresses but not their domain names (198.34.7.1 but not
garcia.netopia.com, for example), verify that the DNS ser ver’s IP address is correct and that it is reachable
from the Netopia R5000 Series Router (use Ping).

If you are using filters, check that your filter sets are not blocking the type of connections you are tr ying to
make.
