Like the subject says I can ping the internal lan but I can't ping external ip addresses.
I know theres probably something I'm missing here so I'm just gonna post some ouptput. Can someone have a look and tell me whats wrong....

when I try the outside world ping returns this:-

gonzo:/home/stinky# ping google.com
PING google.com (216.239.39.99): 56 data bytes
ping: sendto: Network is unreachable
ping: wrote google.com 64 chars, ret=-1

Is your router hooked up with the wizard? I dunno about your setup mines different i got wireless but you go to 192.186.0.1 something like that and it will hook up your internet for your? im guessing you just installed your router? and your linuxbox is the "host" Maybe some more info about your set up will help!

Ok this server is located inside a network where 192.168.1.1 is a gateway linuxbox and this can see the internet fine. Its just this box that can't see the internet.

I'm thinkin that my route table isn't working properly heres the output for the above mentioned server:

gonzo:/home/stinky# route
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
localnet * 255.255.255.0 U 0 0 0 eth0
default crunchy.grunt.n 0.0.0.0 UG 0 0 0 eth0

actually scratch that upon further investigation it looks fine compared to other boxes on the network.

the routing table looks fine . Check the DNS settings .
try pinging an IP on the internet rather that its FQDN.

Pinging external ip address returns the same error:-

ping 216.239.39.99
PING 216.239.39.99 (216.239.39.99): 56 data bytes
ping: sendto: Operation not permitted
ping: wrote 216.239.39.99 64 chars, ret=-1
ping: sendto: Operation not permitted
ping: wrote 216.239.39.99 64 chars, ret=-1


DNS settings are working fine>......

OK your routeing table looks weird if i understand your setup....what is your setup by the way.

Ok so your linuxbox sees the internet and can access it but your windows? box doesnt? how is it all set up linuxbox hooked up to router then cable modem then a windows box off of the router?

Anyways this is my setup i have my linuxbox hooked up the router then the cable modem then wireless windows and this is my routeing tab

root@Darkpunk:~# route
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
192.168.0.0 * 255.255.255.0 U 0 0 0 eth0
loopback * 255.0.0.0 U 0 0 0 lo
default 192.168.0.1 0.0.0.0 UG 0 0 0 eth0

so thats why im saying yours is werid... io may be wrong.... but i would check into how its accessing the internet... a little more about your set up will really help!
