Internet Connection Sharing vs Network Bridge

I have to use a single network connection to provide LAN / WAN to a computer and an Apple TV.

Is it better to use a network bridge or internet connection sharing?

One connection is Gigabit and the other is Ethernet. If I use a bridge will it be degraded to 100Mbs?

what kind of network connection do you have? wired or wireless, public or private.

what hardware you are going to use for bridging?

it sounds like you are connecting wirelessly via computer and use ICS to your ATV.

can you list your network equipment by make and model? I am confused maybe by the terminology you are using.

does you computer use two network cards?

'my lan and wan' is it a router?

'network bridge' is it a switch?

okay got it.

why can't the appletv be connected to the router, too?

so the router is upstairs and a cable runs through the walls to a wall outlet in the room where you computer is. your computer connects to the wall outlet.

you could use a switch connect that to the wall outlet and then connect the computer and the AppleTV to that switch.

I would try ICS with a Crossover Network Cable
