Simple IP Forwarding

[Lucebike]

I now have create an /etc/resolv.conf
with the contents

search
nameserver 192.168.2.1

But from my 2nd computer I cannot ping 192.168.2.1, although I can from my notebook and ip-forwarding on my notebook is enabled and the routing table of the 2nd computer contains the line

Destination Gateway
default 192.168.1.101

(see above for the complete table).
So why does the ping not work...?

I had exactly the same problem you're describing. I followed the instructions found here and my setup is now working smoothly.

Help!

I don't know what is going wrong. I have a hardy heron 8.04 64bit installed and every time I try to route the server hangs up - but not at restart - I even have trouble to restart it with an ctrl+alt+del.

here what I did:
/etc/sysctl.conf deleted the comment to acivate ip forwarding:

net.ipv4.ip_forward = 1

/etc/network/interfaces like this:

# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
auto eth1
iface eth1 inet dhcp

# The secundary network interface for internal network
auto eth0
iface eth0 inet static
address 192.168.1.20
netmask 255.255.255.0
gateway 192.168.1.20
#route add 192.168.1.0 gw 134.xx.yy.zzz

manually added the route, cause in /etc/interfaces, when I uncomment the routing line, the server hangs after a restart of the network:

route add 192.168.1.0 gw 134.xx.yy.zzz

Routing table:
root@cl20:~# netstat -rn

Destination     Gateway         Genmask         Flags   MSS Window  irtt Iface
192.168.1.0     134.xx.yy.zzz   255.255.255.255 UGH       0 0          0 eth1
134.xx.yy.0     0.0.0.0         255.255.255.0   U         0 0          0 eth1
192.168.1.0     0.0.0.0         255.255.255.0   U         0 0          0 eth0
0.0.0.0         134.xx.yy.1     0.0.0.0         UG        0 0          0 eth1
0.0.0.0         192.168.1.20    0.0.0.0         UG        0 0          0 eth0

On my second machine, there is only the internal network. I have activated ip forwarding and configured the route.

What is ugly: this configuration works, but every time I try to /etc/init.d/networking restart

THE SERVER HANGS.
After a reboot it is ok.

What am I doing wrong?
Please help!
