Thumbs up Using linux PC as wireless bridge without using NAT

Hi everybody,

I'm probably going to really show my ignorance with this question.

I have a linux machine working nicely with both wireless and wired cards. I now want to move the machine to another room, and use it to enable other machines without wireless cards to access the lan.

I don't want to use NAT, as I want the other machines to connect with the IP address range etc. (192.168.111.x)

I have managed to bridge the two network interfaces, but that then prevents the machines it self from using the networks.

So what I'm trying to end up with is...

Wireless Router )))))) Linux PC with Wireless ----- Linux PC without Wireless

where both Linux PCs can see the network, and other PCs connected to the wireless router.

Is this possible? If so, how do I do it? If not, any suggestions for achieving a similar result?

... I take it your are connecting the two linux machines via a crossover cable?
You may be better off with IP Forwarding than a bridge. A bit like setting up a gateway.

I've got a spare switch, so I was going to use that.

Thanks for the suggestion. Can IP forwarding be used without NAT? All the references I've seen show it with NAT, but then they're generally sharing an internet connection.
