RL> I have a question that is more of a networking question than a BSD RL> question, but I am hoping someone out there has faced this same dilemma RL> before and has some advice: RL> I have a FreeBSD machine running -current that servers as a router for my RL> home LAN, using nat. I recently tossed in a DLink DWL-G520 wireless card RL> (ath0), and bridged that interface to the internal LAN interface on the RL> machine (rl1). After a bit of configurating, I had the ath interface in RL> hostap mode, and everything was working great - except the wired clients RL> cannot route to eachother. RL> I am suspicious that, since the wired network is in AP mode, if a RL> wireless client wants to send a packet to another wireless client, it RL> must be sent to the AP, which should theoretically redirect the packet RL> to the appropriate host on the wireless net. In the wired network, a RL> switch handles this automagically on the datalink layer without those RL> messages hitting the rl1 interface of the BSD router. I've looked at RL> the bridge code, and it seems that unless a packet is multicast or RL> broadcast it will be copied to the other bridge interfaces but not RL> returned to the original caller. Since the packets being sent between RL> wireless clients are not broadcast, I think they are getting dumped into RL> the black hole of the wired LAN, and not being processed and pumped back RL> out through the ath interface. Is this a correct assumption? Are there RL> ways I can overcome this problem?
