first of all: pls excuse my bad english, I´m german.
So now my problem is, that in network-setup from Zeroshell, I can´t place a default gateway.
Everytime I tried to set it up, and give him the IP of my router (192.168.1.254) it ends up like:
ERROR: Default Gateway not added: gateway 192.168.1.254 is not directly connected.
Ok, but before adding the gateway you need to add an IP belonging to the class 192.168.1.0/24 to the interface directly connected to the router. To Add an IP use the button [Add IP] from the section [Setup]->[Network] of the web interface.
