yesterday i tried to setup my 1043ND running gargoyle v1.9 to use it with TOR. I want to use it in an existing network. DSL comes from a modem and goes into a fritzbox. The fritzbox is dhcp server and provides internet connections for all devices in my Network. What i want to do now is to integrate the 1043ND into this network, preferably with a static IP, and use it as access point (or switch, i dont need wifi) and route the traffic from devices that are connected to the 1043ND through TOR. It is important that the 1043ND is inside the same subnet like any other network device, because i need to access network shares.
Please, could somebody tell me how i have to configure the connection settings in gargoyle?
Here is what i tried:

Im really confused with these settings. What exactly is meant by Router IP? Is it the IP my fritzbox uses, so it would be the same like the Gateway?
