I am using two autonomous 1242's to bridge two wired networks (one AP is root, the other is non-root, no user wireless clients are supported). In this configuration, aren't the AP's bridging at the Layer 2 level (that's what bridges do, right)? From my testing, it didn't seem to matter to the network what IP addresses I assigned to the AP's -- the network was bridged.
If, however, I want to be able to access the AP's https:// interface via computers on the network that the APs are bridging, then do I simply need to assign IP addresses on that same network to the AP's? What about the default-gateway address?
