Hi

I have network problem that can't ping internet but only internal network.
here the configuration.

eth1 server 192.168.1.10 (DNS, IPTAbles, DHCP)
eth0 192.168.0.1 ---> LAN1
eth2 10.0.0.1 ----> lAN2

At the moment the LAN1 if working fine
With the same configuratin on eth2 but I am unable to ping google.com instead only can ping such as DNS.

If I ping the google.com
Ping request can't find host...

Anyone could give some advice.

have you set up the default gateway (your router for internet)? (the 'route' command should give you a row beginning with "default ...")

iptables rules ok ?

tried ping an internet address by ip instead of buy name (to avoid dns problems) ?
