I just got a Cisco 2821. I am currently using both of the integrated gigabit interfaces for routing (one local LAN with NAT, the other is an external subnet).
I was wondering if it is possible to configure the wifi interface (HWIC-AP) to connect to the local lan. If i do so, would i need to clear the ip settings on the local lan gigabit interface, create a bridge bvi1 and then set the ip settings in the bvi1 interface? Then would it work for NAT as well?
I have never done this before, just wondered if that is how it is done. Does anyone have any example configs for these type of routers?
That's it exactly. If you don't need the wireless on the same subnet then you can just put an IP address on the wireless interface.
I don't have an example to hand, sorry. The config is identical (other then interface ID numbers) for all cisco routers and there will be plenty of example 877 configs around I would think. There was an 877 discussion here a few days ago.
