BT-Xbox-Linsys

I don't understand, I go to my BT DNS website, you know the
192.168.1.254. I clicked on Deviced. I showed all deviced connected to
the BT Home Hub and wireless. It showed Unimatrix007 but its visible.
It also showed the BT home HuB which is visual. And some other
devices.

Now I got Linsys RT31P2, It is connected to the HuB's ethernet port 1.
The problem is, it doesn't even detect, read or show the icon in the
Device section. Yes the linksys does feed on the HuB's internet(it
connects to the net).

The problem is, I am trying to connect my Xbox through the linksys. If
I connect my xbox to the linksys using an ethernet cable, my I.P on my
xbox displays 192.168.15.100. But when I connect my Xbox to the HuB
directly to ethernet port 1 the I.P reads 192.168.1.66. With this IP,
I can FTP my xbox to my pc, my Xbox Connect can detect my xbox.
However when I connect my xbox to the linksys, i can't FTP my xbox to
pc nor the Xbox Connect can't find my console. But I can only connect
to the internet.

I need help! so when I connect my xbox to the linksys, I can FTP my
xbox to my pc. Because I can't be using the HuB's ethernet port 1:/

If you know how to do this, drop me a mail:
