Network is unreachable

Linux networking newbie here. I just installed Fedora and everytime I
try to access an exteral IP address, I get "Network is unreachable".
I am using SBC/Yahoo DSL with static IP addresses. I am using the
Cayman/Netopia router. I have set up my server with the IP address
192.168.1.1, gateway 68.248.34.210 (listed as the "static IP gateway
on my reference sheet), and netmask 255.255.255.0. Using the Netopia
configuration tool, I created an IP map, mapping my server's IP
address (192.168.1.1) to one of the static IP addresses supplied by
SBC. I can ping 192.168.1.1, but I can't ping the mapped static
address, nor can I ping anything else (gateway, DNS server, etc).
When I type "netstat -rn" I get:

Destination Gateway Genmask Flags Metric Ref Use Iface
192.168.1.0 * 255.255.255.0 U 0 0 0 eth0
169.254.0.0 * 255.255.0.0 U 0 0 0 eth0

I don't see an entry for the default route. Should I? Reading other
posts, it appears I should. I tried to add one using:

route add -net default gw 68.248.34.210 metric 1

When I try this, I still get "network unreachable".

I do have a Windoze computer attached and getting an IP address
dynamically, it works fine.

Any help would be appreciated.

Your gateway is the IP address of the netopia, 192.168.0.1 ??

Yes, that is right (actually, 192.168.1.254). I was able to add the
default route successfully. I'm still unable to ping a DSN server,
etc. but that is a little farther.

Thanks a lot.

You need a route to 68.248.34.210, and then you can add that address
as a default gateway.

Hi L Lewis,
your computer is supposed to have the router (netopia) as
default gateway. Both should have a similar ip address within
the same subnet. Private ip addresses would include (for example)
the range 192.168.1.1-192.168.1.254 using a 255.255.255.0 subnet.

Your resolv.conf should list the domain name server your
provider gave you.

Then you have to configure your router for internet access, probably
using a webinterface or something.

That's it. I would reset the router to its default values and get
everything working first. You can fool aroung with port forwarding
if you really need it. (remember: your computer offers its services
then to the whole internet - nothing you necessarily want!).

Good luck - and don't fear the penguins!
Peace,
Georg

Hi L Lewis,
have you put the ip of your dns server in resolv.conf?
Just curious, can you post the output of
$ iptables -L
and
$ tcpdump -i eth0 when trying to ping some internet host?

Peace,
Georg
