Hi, i seem to recall from some msg that the Wavelan (the PCMCIA one, supported by the "wi" driver) is unable to transmit pkts with a different MAC address than its own. This would prevent bridging from working at all, unless you implement some workaround (basically encapsulate and decapsulate pkts, kind of "Ethernet-in-Ethernet") at which point you probably can easily forget bridging and go with plain routing/NAT ? Of course you should check with Bill Paul for the correctness of the first sentence. cheers luigi > I haven't bought one yet, but I have become interested lately in > wireless LAN stuff.
