Direct Connect Trough 2 routers Options

[BlastingBout]

Hi ladies and gentleman,

When playing ROTR I can only get the multiplayer to work without using Direct Connect.
Now I know that I can forward the port on the router and that should enable the direct connect option.

But a few things are still not clear to me:

- Do you need to disable upnp when forwarding a port or can it coexist with a forwarded port?
- Which IP adress should I fill in while enabling the port (using both protocols) ?
- Does it only work with a static IP configuration?
- In the options menu of ROTR which IP adress should I select for playing? the 192.168.x.xxx or the 10.xx.xx.xxx etc. (using the 192 gives the serial in use error while joining)

And when this is all cleared out, the main question:

I'm running my UTP cable from PC to the router on the first floor, the router on the first floor is connected with a UTP to the router on ground level, and this router is connected to the modem.
Do I need to format the same port on the ground level router? And what IP adress should I use for that one because it's on a different gateway.

Other multiplayer games run perfectly fine with a really low ping.

THANKS!
