I am installing a new server and have choosen the "private server and gateway" operational mode. The machine a modem for external connections and an ethernet card for internal ones. However I don't seem to be able to connect to the machine from the internal network, I cannot even ping it. I can ping the internal network from the server if I specify the interfacve, like: 'ping -I eth0 xx.xx.xx.xx'.
It feels like some firewall rules are treating the ethernet card as the external connection. Can I check this somewhere somehow, or am I doing something else wrong?
Any help, suggestions, comments and questions are welcome, as I am a little stuck on this one.
