And regular stations can't bridge : (because of differences in the 802.11 frame format depending on whether the : source/destination MAC addresses match the wireless cards or something else). This is true. However, with one AP, it works great. Multiple APs are supported by the Linux hostap driver. : To obtain a real 802.11 bridge, you need the cards to be able to run in : so-called WDS mode, but I'm not even sure this is supported with the PRISM : cards, let alone the Orinocos. No. WDS mode is used for repeaters, not for roaming between APs. : Your only options are: : - route instead of bridging: this requires 3 subnets (one for each LAN and : a /30 for the wireless link), and IP forwarding enabled : - set up some form of tunnel : - a specific case of the above, setup an IPsec VPN between the two boxes. : : Note that the latter options probably require some sort of routing too, or : you'll need to do some fun things with proxy ARP or promiscuous mode somehow... I'm not sure that I follow this advise. It seems to not match with the setup that I'm running right now typing this in.
