Special network configuration on alix 2d13 - help request

[meti]

Hi all. I'm new to openwrt/gargoyle.

I try to integrate my alix 2d13 router into my existing network environment to add a special subnet providing a transparent TOR routing from this new subnet to the internet. Without touching my existing environment.

Existing environment:

FritzBox Router:
- WAN to the internet
- LAN1 to my existing network 192.168.0.0/24
- WLAN1 to my existing network 192.168.0.0/24
- default gateway for my existing network to the internet

Dedicated server:
- dhcp
- dns
- ntp
- fileserver
- printserver

different clients, TV, SAT, ...

Target:
I want to keep my existing network untouched!

The new router (alix 2d13) should provide:
- LAN1 connected to my existing network. default route to my FritzBox router
- a second LAN2 (192.168.1.0/24) which has unlimited access to LAN1 but another default route (192.168.1.1)
- a second WLAN2, maybe bridged to LAN2
- transparent TOR routing for LAN2 and WLAN2
- maybe a LAN3 (192.168.2.0/24) which is completely isolated and has only connection to TOR via SOCKS

The problem is: I don't know how to integrate openwrt/gargoyle into my network because in this setup I have no dedicated WAN interface.
