After I bought the tc, my tv stopped working. I've previously had an ethernet cable to my digital box from my previous router. Didn't work with the tc as my router. So, my isp told me that it -should- be possible to bridge only on port on the tc and connect my digital box to that port. But after reading a bit I don't think its possible to bridge only one lan-port, either the tc is in bridged mode or not.
So i decided to go with a switch instead, and connect the ethernet cable from the telejack to the switch, and connect the switch with the tc and my digital box.
I hope I managed to explain well enough, but my problem should be solved. 🙂
