First, the general question: - if I arping a host behind a bridge device and get the MAC address of the bridge device is this an example of ________________________, while if I arping the same device with another type of bridge I get the MAC address of the actual nic in the host I arpinged this would be an example of transparent bridging? Secondly - the somewhat linux specific side of the mail: I'm using openwrt on a linksys wrt54g as a client to a wireless network which is 64.x.x.x/24. I also have an internal only subnet setup on 192.x.x.x, which I use for devices which do not need to be accessed from the internet regularly. Problem: whatever the bridge [br0] ip network info is set to causes problems for traffic being bridged through it for those IP#'s. For instance if I have br0 set to 192.168.37.120/24, and 192.168.37.1 and .250 try to talk to each other via br0 they stall out and data fails to pass for long periods of time up to a minute or so. However, if I have any other ip traffic such as 64.x.37.x over the bridge it works flawlessly. Apparently the bridge is paying attention to layer 3 and it shouldn't be. BTW - in this instance (probably because most wireless cards in client mode won't "spoof" MAC's, when arpinging something behind this openwrt box it replies with the MAC addy of the wireless interface - if that matters. -- | Ubuntu Linux | www.ubuntulinux.org | | Kubuntu | www.kubuntu.org - : send the line "unsubscribe linux-net" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
