Hi there, and thanks for the reply.
I have already tried bridging, but that didn't seem to help. Infact if i remember correctly it could not even connect to the PC, it went straight to the NAS and detected "older software" (MCE 2005) Then i had the problem of not seeing shares on my PC!!!
The main reason i don't want to go for the switch option, is that the connection from my PC to my nas is a gigabit connection, so when i transfer large files, it only takes a matter of seconds. With a switch data transfer between the two will only reach a max of 10/100 mbps which will reduce its performance 10 fold!! Unless i go for a gigabit hub, which then pushes the price up alot...
