Server pings local but won't ping outside

Hi

I am a newb with enough knowledge to get in trouble! I am running Ubuntu Hardy Server.

I was trying to reconfigure Apache2 and lost my default file. So I decided to 'attempt' to reinstall Apache2 through apt-get and deleting the /etc/apache2 directory. For some reason, I have lost my internet access only from my server.

I have a DSL connection and all the other computers connected access the internet with no problem. My server is the only one that cannot access the internet. From the server I can ping all across the network and can ping the router. But I cannot ping outside the router ONLY FROM THE SERVER! I tried www.google.com and ping 72.14.207.99 - neither work. My /etc/resolv.conf still shows 'nameserver 192.168.1.254' so I know that's ok.

Thanks for the help!

this sounds a lot like you lost your default route for some reason...
can you please post the output of

Code:

---

route -n
cat /etc/network/interfaces

---

hope we can figure this out.

PS: the first command will show your current routing table
the second will show the boot configuration of your network cards.

Here's from route -n

Code:

---

root@wingandrotors:~# route -n
Kernel IP routing table
Destination    Gateway        Genmask        Flags Metric Ref    Use Iface
192.168.1.0    0.0.0.0        255.255.255.0  U    0      0        0 eth0
0.0.0.0        192.168.1.1    0.0.0.0        UG    100    0        0 eth0

and here's /etc/network/interfaces

Code:

---

root@wingandrotors:~# cat /etc/network/interfaces
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

# The loopback network interface
auto lo

# The primary network interface

        address 192.168.1.65
        netmask 255.255.255.0
        network 192.168.1.0
        broadcast 192.168.1.255
        gateway 192.168.1.1

Thanks!

Not sure if this is still an issue for you, but I came across this post whilst having the same issue myself. I thought I should share my solution in case other people are finding this unanswered post.

For me it was a NAT issue. My firewall/router had not automatically set up either dynamic NAT or one to one NAT for the server that was experiencing the problem. Once I configured (in my case) one to one NAT for the server, it all started working. Setting up dynamic NAT would also solve it, but it depends on your needs.
