  • Have you double checked the DHCP configuration, scope, scope and server options to make sure that everything is correct? Have you verified that the clients are getting a valid ip configuration from DHCP?

This looks an awful lot like your DHCP config giving out a bad gateway address (or bad routing options, but that's uncommon).

Are you sharing out DNS servers? 127.0.0.1 is valid on the server, but not for the clients, your DHCP should be sharing out the public IP of the server (192.168.0.1) With the localhost/loopback address you're telling each client that is itself a DNS server (which it isn't, so they don't know how to translate names into IPs).

I guess when you say "network is unreachable" do you mean you cannot ping an external IP, or just when you try to ping by name it fails?
